feat(gps-tracks): ET-008 публичные GPS-треки с публичных платформ

Backend:
- Миграция gps_tracks_001_init.sql: таблицы tracks + pipeline_runs
- Пакет src/api/gps_tracks/: models, db (WAL+upsert с dedup), dedup
  (bbox+length+date bucket-hash), mvt (LRU-кэш 1024 тайла), endpoint
  (GET /api/gps-tracks, GET /api/gps-tracks/tiles/{z}/{x}/{y}.mvt,
   GET /api/gps-tracks/health, POST /api/gps-tracks/cache/clear), config
- Парсеры: osm (split_bbox, haversine, defusedxml XXE-защита),
  enduro_russia + ttrails — заглушки (ADR-010/011 proposed, блокированы)
- Licensing guard: pipeline проверяет status ADR-файла до запуска источника
- scripts/gps_collect.py: CLI с --region/--source/--dry-run/--gc

Frontend:
- src/web/gps_tracks.js: двухрежимный слой (MVT z≤11, GeoJSON z≥12),
  debounced fetch + AbortController, фильтры активности/источника,
  цветовая палитра by-source/by-activity, halo на спутнике, popup трека,
  restorePublicTracksState(), localStorage persistence
- index.html: чекбокс «Публичные треки» в terrain-popup, #sheet-gps-filters
- app.css: .terrain-link-btn, .gps-filter-grid, .track-popup
- app.js: вызов restorePublicTracksState() в rebuildMapOverlays(),
  applyGpsHaloVisibility() в applyBaseLayer()

Конфиги:
- config/gps_sources.yaml: osm (enabled), enduro_russia/ttrails (disabled)
- config/gps_regions.yaml: ЦФО+Чувашия (enabled), Кавказ (disabled)

Docker:
- gps-collector service с profiles: [batch]

Тесты: 48 новых тестов (unit + integration), 125/125 pass
