feat: aviation monitoring layer with flight tracking, airline intel panel, and news feeds (#907)

* feat: Implement comprehensive aviation monitoring service with flight search, status, news, and tracking.

* feat: Introduce Airline Intelligence Panel with aviation data tabs, map components, and localization.

* feat: Implement DeckGL-based map for advanced visualization, D3/SVG fallback, i18n support, and aircraft tracking.

* Update server/worldmonitor/aviation/v1/get-carrier-ops.ts

* feat: Add server-side endpoints for aviation news and aircraft tracking, and introduce a new DeckGLMap component for map visualization.

* Update server/worldmonitor/aviation/v1/list-airport-flights.ts

The cache key for listAirportFlights excludes limit, but the upstream fetch/simulated generator uses limit to determine how many flights to return. If the first request within TTL uses a small limit, larger subsequent requests will be incorrectly capped until cache expiry. Include limit (or a normalized bucket/max) in cacheKey, or always fetch/cache a fixed max then slice per request.

* Update server/worldmonitor/aviation/v1/get-flight-status.ts

getFlightStatus accepts origin, but cacheKey does not include it. This can serve cached results from an origin-less query to an origin-filtered query (or vice versa). Add origin (normalized) to the cache key or apply filtering after fetch to ensure cache correctness.

* feat: Implement DeckGL map for advanced visualization and new aviation data services.

* fix(aviation): prevent cache poisoning and keyboard shortcut in inputs

- get-carrier-ops: move minFlights filter post-cache to avoid cache
  fragmentation (different callers sharing cached full result)
- AviationCommandBar: guard Ctrl+J shortcut so it does not fire when
  focus is inside an INPUT or TEXTAREA element

* feat: introduce AviationCommandBar component for parsing user commands, fetching aviation data, and displaying results.

* feat: Implement aircraft tracking service with OpenSky and simulated data sources.

* feat: introduce DeckGLMap component for WebGL-accelerated map visualizations using deck.gl and maplibre-gl.

* fix(aviation): address code review findings for PR #907

Proto: add missing (sebuf.http.query) annotations on all GET request
fields across 6 proto files; add currency/market fields to
SearchFlightPricesRequest.

Server: add parseStringArray to aviation _shared.ts and apply to
get-airport-ops-summary, get-carrier-ops, list-aviation-news handlers
to prevent crash on comma-separated query params; remove leaked API
token from URL params in travelpayouts_data; fix identical simulated
flight statuses in list-airport-flights; remove unused endDate var;
normalize cache key entity casing in list-aviation-news.

Client: refactor AirlineIntelPanel to extend Panel base class and
register in DEFAULT_PANELS for full/tech/finance variants; fix
AviationCommandBar reference leak with proper destroy() cleanup in
panel-layout; rename priceUsd→priceAmount in display type and all
usages; change auto-refresh to call refresh() instead of loadOps().

* feat: introduce aviation command bar component with aircraft tracking and flight information services.

* feat: Add `AirlineIntelPanel` component for displaying airline operations, flights, carriers, tracking, news, and prices in a tabbed interface.

* feat: Add endpoints for listing airport flights and fetching aviation news.

* Update proto/worldmonitor/aviation/v1/search_flight_prices.proto

Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

* feat: Add server endpoint for listing airport flights and client-side MapPopup types and utilities.

* feat: Introduce MapPopup component with support for various data types and responsive positioning for map features.

* feat: Add initial English localization file (en.json).

* fix(aviation): address PR review findings across aviation stack

- Add User-Agent header to Travelpayouts provider (server convention)
- Use URLSearchParams for API keys instead of raw URL interpolation
- Add input length validation on flightNumber (max 10 chars)
- Replace regex XML parsing with fast-xml-parser in aviation news
- Fix (f as any)._airport type escape with typed Map<FI, string>
- Extract DEFAULT_WATCHED_AIRPORTS constant from hardcoded arrays
- Use event delegation for AirlineIntelPanel price search listener
- Add bootstrap hydration key for flight delays
- Bump OpenSky cache TTL to 120s (anonymous tier rate limit)
- Match DeckGLMap aircraft poll interval to server cache (120s)
- Fix GeoJSON polygon winding order (shoelace check + auto-reversal)

* docs: add aviation env vars to .env.example

AVIATIONSTACK_API, ICAO_API_KEY, TRAVELPAYOUTS_API_TOKEN

* feat: Add aviation news listing API and introduce shared RSS allowed domains.

* fix: add trailing newline to rss-allowed-domains.json, remove unused ringIsClockwise
