Miler rider app: surface system, visible design language, backend lifecycle

Design system
- MilerSurface ladder (canvas → working → raised → floating) with MilerPanel
  as layer 1; canvas moved to #DEE3EA so white separates at 1.290:1.
- Visible vocabulary applied across Home, Deliveries, Activity, Account and
  the sheets: hero heads (tabular numeral + small caption, clamped at 1.3x),
  canvas wells for anything that opens, small filled tags for shelf labels,
  demoted placeholders. Recorded in DESIGN_SYSTEM.md §6.
- One icon family: 222 Material glyphs migrated to Lucide; none left outside
  lib/xpress.
- Colour semantics corrected: amber only for what is genuinely owed, brand red
  reserved for the live stop, disabled primaries go neutral rather than pale.

Data and lifecycle
- lib/data/lifecycle.dart reads mutations for what they prove; route_order.dart
  makes admin sequence the single ordering authority; service_day.dart, and
  stop_area.dart rewritten against live Coimbatore addresses (digit-token
  stripping, city stoplist, street suffixes, stammer collapse).
- countLabel states the load once, in bags.

Testing
- 1440 tests passing; golden shot harnesses for Home, Deliveries, Activity,
  sheets and verify, with test/failures/ now gitignored (diff debris).
- New pins: home_gutter_test, stop_area_test, plus updated structural bounds.

Note: this commit also carries pre-existing working-tree deletions that were
present before this work (API_SPEC.md, README.md, demo test fixtures).
