OpenFlights dataset predates BER's 2020 opening. The patch already
existed in api_server.py for the search UI, but scan_processor.py
uses airports.py directly, so Germany scans silently skipped BER.
Added _MISSING_AIRPORTS to airports.py, patched both
get_airports_for_country() and _all_airports_by_iata() to inject
the extras, making BER available to scans and lookups.

Specific-airports mode scans never resolved full airport names — they
stored the IATA code as destination_name. Fixed in two places:
- airports.py: add lookup_airport(iata) cached helper
- api_server.py: enrich destination_name/city on the fly in the routes
endpoint when the stored value equals the IATA code (fixes all past scans)
- scan_processor.py: resolve airport names at scan time in specific-airports
mode using lookup_airport (fixes future scans at the DB level)
