Adds `deflockapp://node?id=<nodeId>` deep link support: parses the node
ID, fetches the OSM node via the public API, and delivers it via an
`onNodeDeepLink` callback for HomeScreen to register. Includes URL
parsing unit tests.

Extract duplicated retry logic from OverpassService and RoutingService
into a shared resilience framework in service_policy.dart:
- ResiliencePolicy: configurable retries, backoff, and HTTP timeout
- executeWithFallback: retry loop with primary→fallback endpoint chain
- ErrorDisposition enum: abort / fallback / retry classification
- ServicePolicy + ServicePolicyResolver: per-service compliance rules
(rate limits, caching, concurrency) for OSMF and third-party services
- ServiceRateLimiter: async semaphore-based concurrency and rate control
OverpassService now hits overpass.deflock.org first, falls back to
overpass-api.de. RoutingService hits api.dontgetflocked.com first,
falls back to alprwatch.org. Both use per-service error classifiers
to determine retry vs fallback vs abort behavior.

- Add node id tie-breaker to sort comparator so equal-distance nodes
have deterministic ordering across renders (prevents flicker)
- Log validNodesCount instead of allNodes.length so the message
reflects the actual post-filter count

Sort nodes by squared distance from viewport center before applying the
render limit, so visible nodes always make the cut instead of arbitrary
selection causing gaps that shift as you pan.
Also: inject node provider for testability, deduplicate validity filter,
and reduce debug log spam to state transitions only.

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.

Allow offline area downloads for OSM tile server. Move the "downloads
not permitted" check from inside the download dialog to the download
button itself — the button is now disabled (greyed out) when the
current tile type doesn't support offline downloads.

- 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)

Preview/PR builds don't have access to GitHub Secrets, so the OAuth
client IDs are empty. Previously this caused a runtime crash from
keys.dart throwing on empty values. Now we detect missing secrets
and force simulate mode, which already fully supports fake auth
and uploads.
Also fixes a latent bug where forceLogin() would crash with
LateInitializationError in simulate mode since _helper is never
initialized when OAuth setup is skipped.

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.
