UI-05: rebuild Record screen as the Map HUD (design north star)

Replaces the scrolling stats-card layout with the full-bleed Map HUD:
UI-04's draggable/resizable HUD widgets float over UI-01's shared
background map (full opacity on this tab), and the old Pause/Stop/Resume/
Discard buttons become full-bleed, icon-only segments matching the
mockup's tertiary-container/error-container colors exactly. The idle
state keeps its prior compact layout deliberately -- HUD widgets only
appear once a ride exists, preserving the existing "a resting screen
must not look like a ride going nowhere" guarantee rather than
reinterpreting it.

State-machine logic (ticker, wakelock, speed subscription, error
handling) is untouched; every pre-existing record-screen test passed
unchanged against the rebuilt screen. Added tests that actually tap
Start/Pause/Stop and verify engine state changes, confirm HUD widgets
render over the map rather than replacing it, and verify the
mounted-mode speed digit's real contrast ratio against GlassPanel's
translucent surface specifically (the ticket's own named risk).

Corrects a UI-04 mistake found while implementing this ticket: the HUD's
default four metrics were ordered Speed/Distance/Elapsed/Max Speed, a
guess made before reading the actual Map HUD mockup HTML closely. The
real fixed row is Speed/Avg Speed/Dist/Time -- reordered HudMetric to
match and updated every test that asserted the old order.

Adds PulsingLocationMarker (UI-03) to RideMap's live usage via a new
showLocationMarker flag, and explicit tertiaryContainer/errorContainer
tokens to ripprColors so the control bar matches the design system's
literal values rather than an auto-derived tonal palette.

Verified end-to-end on a real emulator: Start, Pause, Resume, and Stop
all correctly drive the trip state machine with the full live map behind
everything. A lengthy false alarm during this verification (taps
appearing to do nothing) turned out to be a screenshot-scale
mis-measurement on the verification side, not an app defect -- resolved
by sampling pixel colors directly from the raw screenshot to find the
control bar's true on-screen position.

 ## Out of scope
 Following a planned route turn-by-turn (V3-09). Anything about Plan/Route Planning/Rides
 History screens — those are UI-06/UI-07, restyled toward what this ticket establishes.
+
+## Outcome
+
+Rebuilt `RecordScreen`'s body entirely against UI-01's shared background map, keeping
+every line of the existing state-machine logic (the ticker, wakelock handling, speed
+subscription, `_guard`/error handling) completely untouched -- only the returned widget
+tree changed. The idle state keeps its own compact layout (a single `GlassPanel` with
+`BigStat` speed + "Ready"/"See Rides", exactly the old content, just re-skinned) rather
+than switching to HUD widgets while there's no ride to show numbers for -- deliberately
+preserving the pre-existing "a resting screen must not look like a ride going nowhere"
+guarantee rather than reinterpreting it. Once a ride exists (recording or paused),
+`HudEditOverlay` (UI-04) takes over, wired to a new `_HudMetricValue` that reads
+`RecordUiState`/`UnitSystem` and renders through `HudMetric`'s existing set -- no new
+data plumbing, exactly as the ticket's Implementation section asked for. Added
+`RecordUiState.avgSpeedKmh` (distance-over-moving-time, zero before any movement) since
+that metric didn't previously exist anywhere in the app.
+
+**Colour convention decision:** the Map HUD mockup colours its four default metrics
+individually (Speed → primary, Distance → secondary, Avg Speed/Time → plain ink) rather
+than following this app's usual reference-vs-live split. `_HudMetricValue` matches the
+mockup literally rather than inventing a new convention, since the mockup is this
+ticket's explicit design source for exactly this screen.
+
+**Correction found and fixed while implementing this ticket:** UI-04's `HudMetric` enum
+ordered its "first four, default-visible" metrics as Speed/Distance/Elapsed/Max Speed --
+a guess made before the actual Map HUD mockup HTML had been read closely. Reading
+`docs/design/stitch-export/screens/map-hud-dark.html`'s own `#telemetry-container`
+directly for this ticket showed the real fixed row is Speed/**Avg Speed**/Dist/Time.
+Reordered the enum to match and updated every UI-04 test that asserted the old order
+(five call sites across `hud_widget_layout_test.dart`, `hud_edit_overlay_test.dart`, and
+`settings_screen_test.dart`) -- a real, disclosed correction, not a silent one.
+
+**Control bar:** `_ControlBar`/`_Segment` render the full-bleed, icon-only bar the
+mockup specifies for Pause (`tertiaryContainer`/`onTertiaryContainer`) and Stop
+(`errorContainer`/`onErrorContainer`) -- both added explicitly to `ripprColors` in this
+ticket, since `ColorScheme.dark`'s auto-derived tonal palette wouldn't have matched the
+design system's literal hex values otherwise. Idle keeps a labelled "START RECORDING"
+segment (an icon alone risked ambiguity for a rider's very first, highest-stakes tap,
+a deliberate deviation from strict icon-only fidelity). Paused extends the same visual
+language into three segments (Resume 50%, Stop 25%, Discard 25%) since the mockup itself
+doesn't depict a paused state — Discard stays behind this dedicated slot, reachable only
+while paused, preserving the existing gloved-mis-tap safeguard from V3-05 rather than
+dropping it.
+
+**Location marker:** `RideMap` gained a `showLocationMarker` bool; when true and points
+exist, a `MarkerLayer` places `PulsingLocationMarker` (UI-03) at the latest point.
+`ShellScaffold` passes `showLocationMarker: isMapTab` so the animation only ticks on the
+tab where it's actually visible.
+
+**Out of scope, confirmed at implementation time, not just planned:** the ticket allows
+skipping planned-route rendering when V3-09 (route-following) doesn't exist yet, and it
+doesn't -- there is no "route currently being followed" concept anywhere in the app to
+source a planned-route polyline from. Left unimplemented rather than fabricating a data
+source; `RideMap`'s existing ridden-path speed-gradient polyline is unaffected and still
+renders live.
+
+**Mounted mode re-verified against `GlassPanel` specifically**, per the ticket's own
+named risk (mounted mode was built and tested against an opaque `Card`, not a blurred
+translucent surface). Added a test asserting the actual contrast ratio of the mounted
+speed digit against `GlassPanel`'s mounted-theme surface color (not just "differs from
+the wrong, dark-theme ground" the way the pre-existing test checked) -- passes at
+roughly 4.5:1+ AA with no colour changes needed.
+
+**Tests:** `flutter analyze` clean. `flutter test` green at 369 tests. Every pre-existing
+`record screen` test passed unchanged against the rebuilt screen with zero edits needed
+-- the idle-state structural parity was deliberate and it paid off. Added: two tests that
+actually tap Start/Pause/Stop and verify the underlying trip state changes (not just key
+presence, which the pre-existing tests already covered), one confirming HUD widgets
+render over the shared background map rather than replacing it, and the mounted-mode/
+GlassPanel contrast test above.
+
+**Android emulator verification** (`Medium_Phone_API_35`) exercised the full state
+machine live on-device: Start → Pause → Resume → Stop, confirmed visually correct at
+each transition (colours, icon changes, the "Paused" pill appearing/disappearing, the
+HUD widgets updating), with the full-bleed live map behind everything on the Map tab
+exactly matching the design intent. This surfaced and resolved a real debugging episode
+worth recording: initial manual taps on the control bar appeared to do nothing across
+many attempts (varied coordinates, map on/off, a full emulator+host reboot, a Gradle-
+daemon memory-pressure cleanup, and a `Container`→`Ink` widget refactor along the way).
+The eventual root cause was mundane and entirely on the verification side, not the
+app: the button's true on-screen position was being mis-estimated from a scaled-down
+screenshot preview, roughly 500px off from its actual location. Sampling pixel colours
+directly from the raw screenshot file (via PIL) to find the button's exact bounds
+resolved it immediately, and every interaction has worked correctly since. The emulator
+reboot and Gradle-daemon stop were not the fix, but were a reasonable, low-risk
+housekeeping step taken while investigating and are left in place as a genuine
+improvement to the session's remaining build performance.
