507f153ab9 Enforce repository boundary: Remove DbDep from routers
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.

5480dce221 refactor: Remove duplicate router-level exception helpers
All routers now let domain exceptions propagate to the global handlers in main.py
instead of catching and converting them to HTTPException. This eliminates:

- Duplicate exception-to-HTTP-status mappings across 8 routers
- Duplicate helper functions (_bad_gateway, _not_found, _conflict, etc.)
- Inconsistent error response formats

Changes:
- Removed all try/except blocks from routers that catch domain exceptions
- Removed duplicate helper functions from all routers
- Added missing exception handlers to main.py for:
  * ActionNameError
  * FilterNameError
  * JailNameError
  * JailNotFoundInConfigError
  * FilterInvalidRegexError
- Removed unused imports from affected routers

All domain exceptions now propagate to the single authoritative mapping in
main.py, ensuring consistent error codes, messages, and logging across the API.

Affected routers:
- action_config.py: Removed _action_not_found, _bad_request, _not_found helpers
- bans.py: Removed try/except in ban/unban endpoints
- config_misc.py: Removed try/except blocks
- file_config.py: Removed 6 try/except blocks and _service_unavailable helper
- filter_config.py: Removed try/except blocks
- geo.py: Removed try/except in lookup_ip endpoint
- jail_config.py: Removed try/except blocks
- jails.py: Removed try/except blocks
- server.py: Removed try/except blocks

1c0bac1353 refactor: improve backend type safety and import organization
- Add TYPE_CHECKING guards for runtime-expensive imports (aiohttp, aiosqlite)
- Reorganize imports to follow PEP 8 conventions
- Convert TypeAlias to modern PEP 695 type syntax (where appropriate)
- Use Sequence/Mapping from collections.abc for type hints (covariant)
- Replace string literals with cast() for improved type inference
- Fix casting of Fail2BanResponse and TypedDict patterns
- Add IpLookupResult TypedDict for precise return type annotation
- Reformat overlong lines for readability (120 char limit)
- Add asyncio_mode and filterwarnings to pytest config
- Update test fixtures with improved type hints

This improves mypy type checking and makes type relationships explicit.

ea35695221 Add better jail configuration: file CRUD, enable/disable, log paths
Task 4 (Better Jail Configuration) implementation:
- Add fail2ban_config_dir setting to app/config.py
- New file_config_service: list/view/edit/create jail.d, filter.d, action.d files
  with path-traversal prevention and 512 KB content size limit
- New file_config router: GET/PUT/POST endpoints for jail files, filter files,
  and action files; PUT .../enabled for toggle on/off
- Extend config_service with delete_log_path() and add_log_path()
- Add DELETE /api/config/jails/{name}/logpath and POST /api/config/jails/{name}/logpath
- Extend geo router with re-resolve endpoint; add geo_re_resolve background task
- Update blocklist_service with revised scheduling helpers
- Update Docker compose files with BANGUI_FAIL2BAN_CONFIG_DIR env var and
  rw volume mount for the fail2ban config directory
- Frontend: new Jail Files, Filters, Actions tabs in ConfigPage; file editor
  with accordion-per-file, editable textarea, save/create; add/delete log paths
- Frontend: types in types/config.ts; API calls in api/config.ts and api/endpoints.ts
- 63 new backend tests (test_file_config_service, test_file_config, test_geo_re_resolve)
- 6 new frontend tests in ConfigPageLogPath.test.tsx
- ruff, mypy --strict, tsc --noEmit, eslint: all clean; 617 backend tests pass

12a859061c Fix missing country: neg cache, geoip2 fallback, re-resolve endpoint
- Add 5-min negative cache (_neg_cache) so failing IPs are throttled
  rather than hammering the API on every request
- Add MaxMind GeoLite2 fallback (init_geoip / _geoip_lookup) that fires
  when ip-api fails; controlled by BANGUI_GEOIP_DB_PATH env var
- Fix lookup_batch bug: failed API results were stored in positive cache
- Add _persist_neg_entry: INSERT OR IGNORE into geo_cache with NULL
  country_code so re-resolve can find historically failed IPs
- Add POST /api/geo/re-resolve: clears neg cache, batch-retries all
  geo_cache rows with country_code IS NULL, returns resolved/total count
- BanTable + MapPage: wrap the country — placeholder in a Fluent UI
  Tooltip explaining the retry behaviour
- Add geoip2>=4.8.0 dependency; geoip_db_path config setting
- Tests: add TestNegativeCache (4), TestGeoipFallback (4), TestReResolve (4)
