Snapshot: MLS sync fixes, image refresh, plugin/theme updates

MLS plugin fixes from this session:
- Fix silent insert failures: location column NOT NULL was rejecting wpdb->insert calls,
  causing ~18k new properties since Dec 2025 to be lost. Inserts now build raw SQL
  with ST_PointFromText so the spatial column is populated atomically.
- Auto-refresh expired media URLs in MLS_Media_Handler::fetch_and_cache(), guarded by
  a property-level GET_LOCK so concurrent fetches share one API refresh.
- Normalize WP_Error to null in mls_get_property_image() so callers can rely on the
  documented string|null contract.
- Support comma-separated property_type filters in MLS_Query and MLS_Cluster so the
  homepage "View All Commercial" link (?property_type=Commercial+Sale,Land,Farm)
  actually filters correctly.
- Incremental sync now looks back 10 minutes past the latest modification timestamp
  as a safety margin against missed records.
- Smart sync exits silently (info-level, not warning) when a full sync is in progress.

Operational:
- New cron: weekly full sync Sundays at 3 AM (/usr/local/bin/mls-full-sync).
- New cron: hourly 2GB cap on mls-thumbnails/ and cache/transformed-images/
  (/usr/local/bin/mls-image-cache-cap).
- Logrotate config for wp-content/debug.log (2-day retention, daily rotation,
  delaycompress).

Repo policy:
- CLAUDE.md updated with explicit "commit everything except build artifacts" policy.
- .gitignore: untrack runtime image caches and debug.log rotations.

Other modifications in this snapshot are pre-existing in-flight theme/plugin/db_content_updates work.
