feat: standardise recheck availability to JSONL output

- extract_recheck() now writes availability_{date}_recheck_{HH}.jsonl.gz
  (one venue per line with date/captured_at_utc/recheck_hour injected);
  uses compress_jsonl_atomic; removes write_gzip_atomic import
- stg_playtomic_availability: add recheck_jsonl CTE (newline_delimited
  read_json on *.jsonl.gz recheck files); include in all_venues UNION ALL;
  old recheck_blob CTE kept for transition
- init_landing_seeds.py: add JSONL recheck seed alongside blob seed
- Docs: README landing structure + data sources table updated; CHANGELOG
  availability bullets updated; data-sources-inventory paths corrected

@@ -9,7 +9,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
 ### Added
 - **JSONL streaming landing format** — extractors now write one JSON object per line (`.jsonl.gz`) instead of a single large blob, eliminating in-memory accumulation and `maximum_object_size` workarounds:
   - `playtomic_tenants.py` → `tenants.jsonl.gz` (one tenant per line; dedup still happens in memory before write)
-  - `playtomic_availability.py` → `availability_{date}.jsonl.gz` (one venue per line with `date`/`captured_at_utc` injected; working file IS the final file — eliminates the consolidation step)
+  - `playtomic_availability.py` → `availability_{date}.jsonl.gz` (morning) + `availability_{date}_recheck_{HH}.jsonl.gz` (recheck); one venue per line with `date`/`captured_at_utc`/`recheck_hour` injected
   - `geonames.py` → `cities_global.jsonl.gz` (one city per line; eliminates 30 MB blob and its `maximum_object_size` workaround)
   - `compress_jsonl_atomic(jsonl_path, dest_path)` utility added to `utils.py` — streams compression in 1 MB chunks, atomic `.tmp` rename, deletes source
 - **Regional Overpass splitting for tennis courts** — replaces single global query (150K+ elements, timed out) with 10 regional bbox queries (~10-40K elements each, 150s server / 180s client):

 ### Changed
 - All modified staging SQL models use **UNION ALL transition CTEs** — both JSONL (new) and blob (old) formats are readable simultaneously; old `.json.gz` files in the landing zone continue working until they rotate out naturally:
   - `stg_playtomic_venues`, `stg_playtomic_resources`, `stg_playtomic_opening_hours` — JSONL top-level columns (no `UNNEST(tenants)`)
-  - `stg_playtomic_availability` — JSONL morning files + blob morning files + blob recheck files
+  - `stg_playtomic_availability` — JSONL morning + recheck files; blob morning + recheck kept for transition
   - `stg_population_geonames` — JSONL city rows (no `UNNEST(rows)`, no `maximum_object_size`)
   - `stg_tennis_courts` — JSONL elements with `COALESCE(lat, center.lat)` for way/relation centre coords; blob UNNEST kept for old files
 - **Marketplace admin dashboard** (`/admin/marketplace`) — single-screen health view for the two-sided market:
