The coord-validation and antimeridian-unwrap logic added in the last
pass had been duplicated across map.ts, trail_manager.ts, and
info_map.ts. Move both into map_helpers.ts and import from there so
there is one authoritative implementation.
- Heatmap: filter points with invalid coords or out-of-range intensity
so malformed rows can't distort the layer.
- InfoMap: validate coords for range (not just NaN) and use an epsilon
when comparing positions, so float noise doesn't cause needless
re-renders or accept bogus data.
- TrailManager: getTrailCenter returns null for empty input instead of
the ambiguous (0, 0) null-island; callers guard accordingly.
Convert app.js, info_map.js, error_boundary.js, and time_ago_hook.js
to TypeScript with proper typing for Phoenix hooks, Leaflet, DOM
interactions, and timer management. Update esbuild hex package to
~> 0.10 and binary to 0.25.4. Entry point changed to app.ts.
- Add DOM existence check before reinitializing map
- Implement initialization flag to prevent race conditions
- Improve cleanup in destroyed() to prevent memory leaks
- Map now only updates marker position when location changes
- Fix zero coordinate handling to distinguish between invalid coordinates and valid 0.0 (equator/prime meridian)
- Add to_float_safe() function that preserves nil for proper coordinate validation
- Add comprehensive coordinate validation with descriptive logging in JavaScript
- Make position change threshold configurable via application config (default: 0.001°)
- Add extensive test coverage for edge cases including nil coordinates and equator crossing
- Improve robustness for real-world APRS coordinate edge cases

- Optimize LiveView to only update position data when coordinates actually change (>100m threshold)
- Hide loading spinner after map initialization to prevent flash on updates
- Add position change detection logic with proper nil/Decimal handling
- Add comprehensive test coverage for position change detection
- Maintain smooth map animations and existing functionality
Resolves map flashing and unnecessary reloads when new packets arrive on /info/:call pages.

- Fixed info page not receiving live updates by implementing callsign-specific PubSub topics
- Added automatic time counter for "Last Position" and other timestamps using JavaScript hook
- Optimized map updates to only move marker instead of reloading entire map
- Fixed APRS parser to properly handle [000/000/A=altitude format in comments
- Removed packet caching on info page for real-time updates
The info page now properly subscribes to updates for the specific callsign being viewed,
timestamps automatically count up without page refresh, and the map smoothly animates
marker position changes instead of flickering with full reloads.
