Add waypoint list panel and bottom stats bar

Browse Source 
- BottomStatsBar: persistent "Details: N WP · dist m · duration" pill
  (HTML prototype's #bottomBar/#statsRow), tap opens the full waypoint
  list. Mission/drone name and the Send button are intentionally not part
  of this - mission library and upload aren't wired up yet.
- A warn banner ("Route exceeds drone capabilities at highlighted point")
  appears above it whenever buildRouteGeometry finds a bad vertex or leg -
  a direct, low-effort payoff from the fillet geometry work.
- WaypointListPanel: full-screen overlay listing every waypoint
  (altitude/speed/execute/catch radius), matching the prototype's List
  tab. Only one row editable at a time; editing swaps plain text for
  draggable WaypointChip values and an execute dropdown. Row tap (outside
  edit mode) centers the map on that waypoint and closes the panel; delete
  removes it and adjusts the reticle's target index the same way the halo
  menu's remove already does.
- WaypointChip: vertical-drag value chip (HTML prototype's .value-chip),
  fixed step of 10 per 14px matching chipFieldConfig - simpler than the
  original's dual vertical/horizontal axis-lock gesture, which felt like
  more fidelity than the interaction warrants here.
- Provider gained setCatchRadius and setAction (direct assignment, as
  opposed to toggleAction's toggle-to-none semantics used by the halo
  menu) to support the list's editable fields.
- Altitude/Speed full-chart tabs from the prototype (drag-to-adjust
  altitude/speed profile charts) are a separate, larger feature and not
  part of this step.

Centering on a waypoint from the list calls MapController.move(), which -
like the reticle's auto-snap - doesn't emit MoveEnd, so snap detection is
invoked manually afterward to match the prototype's resulting behavior.

Added 4 widget tests (open empty list, row-tap centers and closes, delete
removes and updates the empty state, chip drag updates altitude) - one
required a pump(duration) after the drag to flush the chip's 120ms flash
Timer, which was otherwise still pending at test teardown. All 15 tests
and flutter analyze pass. Manually verified on the Pixel_10a emulator:
opened the list with two waypoints, edited a row's altitude via chip drag
(confirmed value change, accounting for device-pixel-ratio scaling vs the
widget-test logical-pixel case), and confirmed row-tap re-centers/closes.
