flights v2: implement redesign

Migrate src/features/flights to the v2 tactical-ops design — the last
page still on the legacy az-* palette — keeping all existing planner
behavior (Leaflet map, draw modes, import/export, altitude dialog).

- Restyle every flights surface to v2 tokens and shared classes:
  flight roster sidebar (search, rows, telemetry card), params panel,
  waypoint list, altitude/JSON dialogs, map-point popup, altitude
  chart, wind inputs, mini-map.
- Rebuild the params panel to the mockup order (draw-mode selector,
  Mission Config, Waypoints) with existing controls appended.
- Add HUD overlays on the real Leaflet map (telemetry, legend, compass,
  zoom/recenter toolbar, bottom status strip); disable the default zoom
  control, add a dark tactical-grid backdrop, and use the legend glyphs
  (diamond/square/octagon) plus a pulsing amber current-position beacon.
- Add a functional GPS-Denied panel: orthophoto upload (local),
  live-GPS readout fed by the existing SSE stream, and a GPS-correction
  form that patches waypoint coordinates.
- Extract a shared drawModes config used by the panel and collapse rail.
- Add flights.v2 i18n keys to en.json and ua.json (parity preserved).
