- DB schema: relaxed origin CHECK to >=2 chars, added scan_mode column to
scans and scheduled_scans, added origin_airport to routes and flights,
updated unique index to (scan_id, COALESCE(origin_airport,''), destination)
- Migrations: init_db.py recreates tables and adds columns via guarded ALTERs
- API: scan_mode field on ScanRequest/Scan; Route/Flight expose origin_airport;
GET /scans/{id}/flights accepts origin_airport filter; CreateScheduleRequest
and Schedule carry scan_mode; scheduler and run-now pass scan_mode through
- scan_processor: _write_route_incremental accepts origin_airport; process_scan
branches on scan_mode=reverse (country → airports × destinations × dates)
- Frontend: new CountrySelect component (populated from GET /api/v1/countries);
Scans page adds Direction toggle + CountrySelect for both modes; ScanDetails
shows Origin column for reverse scans and uses composite route keys; Re-run
preserves scan_mode

- Change API ORDER BY from price/date to date/price (chronological default)
- Add flightSortField/flightSortDir state to ScanDetails
- Make Date and Price sub-table headers clickable with sort icons

Users running large scans can now pause (keep partial results, resume
later), cancel (stop permanently, partial results preserved), or resume
a paused scan which races through cache hits before continuing.
Backend:
- Extend scans.status CHECK to include 'paused' and 'cancelled'
- Add _migrate_add_pause_cancel_status() table-recreation migration
- scan_processor: _running_tasks/_cancel_reasons registries,
cancel_scan_task/pause_scan_task/stop_scan_task helpers,
CancelledError handler in process_scan(), start_resume_processor()
- api_server: POST /scans/{id}/pause|cancel|resume endpoints with
rate limits (30/min pause+cancel, 10/min resume); list_scans now
accepts paused/cancelled as status filter values
Frontend:
- Scan.status type extended with 'paused' | 'cancelled'
- scanApi.pause/cancel/resume added
- StatusChip: amber PauseCircle chip for paused, grey Ban for cancelled
- ScanDetails: context-aware action row with inline-confirm for
Pause and Cancel; Resume button for paused scans
Tests: 129 total (58 new) across test_scan_control.py,
test_scan_processor_control.py, and additions to existing suites

- New `scheduled_scans` table with daily/weekly/monthly frequencies
- asyncio background scheduler loop checks for due schedules every 60s
- 6 REST endpoints: CRUD + toggle enabled + run-now
- `scheduled_scan_id` FK added to scans table; migrated automatically
- Frontend: Schedules page (list + create form), Schedules nav link,
"Scheduled" badge on ScanDetails when scan was triggered by a schedule

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)

Backend:
- DELETE /api/v1/scans/{id} — 204 on success, 404 if missing,
409 if pending/running; CASCADE removes routes and flights
Frontend (api.ts):
- scanApi.delete(id)
Frontend (ScanDetails.tsx):
- Re-run button: derives window_months from stored dates, detects
country vs airports mode via comma in scan.country, creates new
scan and navigates to it; disabled while scan is active
- Delete button: inline two-step confirm (no modal), navigates to
dashboard on success; disabled while scan is active

- Rewrite airport search to use priority buckets instead of simple
append: exact IATA → IATA prefix → city prefix → city contains →
name prefix → name contains → country match. This ensures BER
appears before Berlin-Schönefeld when typing "BER".
- Add _MISSING_AIRPORTS patch list to get_airport_data() so airports
absent from the OpenFlights dataset (e.g. BER opened Nov 2020,
IST new Istanbul airport) are included at runtime.
- Deduplicate results via seen-set to avoid duplicate entries.
