When a user edits a tile type's URL template, max zoom, or API key
without changing IDs, the cached DeflockTileProvider would keep the old
frozen config. Now _getOrCreateProvider() computes a config fingerprint
and replaces the provider when drift is detected.

- Add ServicePolicy framework with OSM-specific rate limiting and TTL
- Add per-provider disk tile cache (ProviderTileCacheStore) with O(1)
lookup, oldest-modified eviction, and ETag/304 revalidation
- Rewrite DeflockTileProvider with two paths: common (NetworkTileProvider)
and offline-first (disk cache -> local tiles -> network with caching)
- Add zoom-aware offline routing so tiles outside offline area zoom ranges
use the efficient common path instead of the overhead-heavy offline path
- Fix HTTP client lifecycle: dispose() is now a no-op for flutter_map
widget recycling; shutdown() handles permanent teardown
- Add TileLayerManager with exponential backoff retry (2s->60s cap),
provider switch detection, and backoff reset
- Guard null provider/tileType in download dialog with localized error
- Fix Nominatim cache key to use normalized viewbox values
- Comprehensive test coverage (1800+ lines across 6 test files)

Replace our custom tile pipeline (fetchRemoteTile / _SimpleSemaphore /
exponential backoff) with flutter_map's built-in NetworkTileProvider,
gaining persistent disk cache, ETag revalidation, RetryClient, and
obsolete request aborting for free.
DeflockTileProvider now extends NetworkTileProvider and overrides
getTileUrl() to route through TileType.getTileUrl() (quadkey,
subdomains, API keys). getImageWithCancelLoadingSupport() routes
between two paths at runtime: the common network path (super) when
no offline areas exist, and a DeflockOfflineTileImageProvider for
offline-first when they do.
- Delete tiles_from_remote.dart (semaphore, retry loop, spatial helpers)
- Simplify MapDataProvider._fetchRemoteTileFromCurrentProvider to plain
http.get (only used by offline area downloader now)
- Remove dead clearTileQueue/clearTileQueueSelective from MapDataProvider
- Remove 7 tile fetch constants from dev_config.dart
- TileLayerManager now disposes provider on cache clear and uses actual
urlTemplate for cache key generation
- 9 new tests covering URL delegation, routing, and equality
Closes#87 Phase 2.

Cancel in-progress follow-me animations on pointer-down and suppress
new ones while any pointer is on the map. Without this, GPS position
updates trigger 600ms animateTo() calls that fight with the user's
stationary finger, causing visible wiggle — especially at low zoom
where small geographic shifts cover more pixels.

Migrate all withOpacity() calls to withValues(alpha:) and
surfaceVariant to surfaceContainerHighest across the codebase.
