UI-07: rebuild Rides History with search, activity filter, and real ride thumbnails

Restyles TripsScreen toward Map HUD's GlassPanel language: a search bar and
activity-filter dropdown, four distinct summary stat cards (replacing the
mockup's four-identical-cards artifact), and per-ride RideMap thumbnails
showing each ride's own recorded path instead of stock photos.

RideHistorySummary is a pure function rather than a provider, since folding
over an already-fetched trip list is cheap regardless of history length, and
it makes the aggregation directly unit-testable. Average speed is
distance-weighted across the whole history rather than averaging each ride's
own average.

Adds a showAttribution flag to RideMap (default true) to suppress the
TileAttribution control on tiny list thumbnails, where it was both a UX
problem and a test collision with each card's own activity icon.
