This commit enforces the repository boundary by eliminating direct database connection
dependencies (DbDep) from all routers. Routers now depend on service context dependencies
that combine the database connection with the related repositories.
Changes:
- Add 5 service context dependencies in dependencies.py:
* SessionServiceContext: db + session_repo
* BlocklistServiceContext: db + blocklist_repo + import_log_repo + settings_repo
* SettingsServiceContext: db + settings_repo
* BanServiceContext: db + fail2ban_db_repo
* HistoryServiceContext: db + fail2ban_db_repo + history_archive_repo
- Refactor all 9 routers (auth, bans, blocklist, config_misc, dashboard, geo,
history, jails, setup) to use service contexts instead of DbDep.
- Update Backend-Development.md with clear examples of the new pattern and
documentation of available service contexts.
Rationale:
- Enforces the repository boundary through the dependency system
- Makes database operations explicit and auditable
- Improves testability by allowing service contexts to be mocked
- Prevents accidental direct database access from routers
The deprecated DbDep remains available for backward compatibility with
services that have not yet been refactored, but routers can no longer import it.

Instead of returning a bound method (geo_cache.lookup_batch), now inject
the GeoCache instance directly into routers and services. This provides
proper runtime isolation since T-04 made GeoCache a proper object.
Changes:
- Remove get_geo_batch_lookup() dependency provider
- Add GeoCacheDep type alias for injecting GeoCache instances
- Update all routers (bans, blocklist, dashboard, jails) to use GeoCacheDep
- Update ban_service, blocklist_service, jail_service to accept GeoCache
- Update service protocols to match new signatures
- Update docstrings to reference GeoCache methods instead of module functions
All callers now call geo_cache.lookup_batch(...) directly instead of
geo_batch_lookup(...), providing real dependency injection with proper
testing isolation.
