Fix missing country: neg cache, geoip2 fallback, re-resolve endpoint

Browse Source 
- 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)

## Task 4 — Fix Missing Country for Resolved IPs
## Task 4 — Fix Missing Country for Resolved IPs ✅ DONE
**Completed:**
- `geo_service.py`: Added `_neg_cache: dict[str, float]` with 5-minute TTL (`_NEG_CACHE_TTL = 300`). Failed lookups (any cause) are written to the neg cache and returned immediately without querying the API until the TTL expires. `clear_neg_cache()` flushes it (used by the re-resolve endpoint).
- `geo_service.py`: Added `init_geoip(mmdb_path)` + `_geoip_lookup(ip)` using `geoip2.database.Reader`. When ip-api fails, the local GeoLite2-Country `.mmdb` is tried as fallback. Only fires if `BANGUI_GEOIP_DB_PATH` is set and the file exists; otherwise silently skipped.
- `geo_service.py`: Fixed `lookup_batch()` bug where failed API results were stored in the positive in-memory cache (`_store` was called unconditionally). Now only positive results go into `_cache`; failures try geoip2 fallback then go into `_neg_cache`.
- `geo_service.py`: Added `_persist_neg_entry(db, ip)` — `INSERT OR IGNORE` into `geo_cache` with `country_code=NULL` so the re-resolve endpoint can find previously failed IPs without overwriting existing positive entries.
- `config.py`: Added `geoip_db_path: str | None` setting (env `BANGUI_GEOIP_DB_PATH`).
- `pyproject.toml`: Added `geoip2>=4.8.0` dependency.
- `main.py`: Calls `geo_service.init_geoip(settings.geoip_db_path)` during lifespan startup.
- `routers/geo.py`: Added `POST /api/geo/re-resolve` — queries `geo_cache WHERE country_code IS NULL`, clears neg cache, batch-re-resolves all those IPs, returns `{"resolved": N, "total": M}`.
- `BanTable.tsx`: Country cell now wraps the `—` placeholder in a Fluent UI Tooltip with message "Country could not be resolved — will retry automatically."
- `MapPage.tsx`: Same Tooltip treatment for the `—` placeholder in the companion table.
- Tests: Updated `test_geo_service.py` — removed outdated `result is None` assertions (lookup now always returns GeoInfo), updated neg-cache test, added `TestNegativeCache` (4 tests) and `TestGeoipFallback` (4 tests). Added `TestReResolve` (4 tests) in `test_geo.py`. **430 total tests pass.**
