Add support for comma-separated POTA references across the app: bump migration version to 259 and add migration 260 to expand COL_MY_POTA_REF and station_pota to VARCHAR(255). Introduce Pota::split_refs and collect_refs_from_rows to normalize and aggregate multiple refs; refactor Pota counts to compute unique refs per band/mode. Normalize station_pota when saving in Stations and Logbook_model (uses normalize_pota_refs), and adjust POTA search to match refs inside comma-separated values. Update views to render multiple POTA links and hashtags, and add Selectize-based autocomplete for station POTA input on create/edit forms. Also minor change to user_owns_station query (removed user_id where clause).
Introduces a new POTA awards dashboard with HTMX-powered filtering, statistics, progress bars, and a Leaflet map of worked parks. Adds new controller endpoints, model methods for filtered queries and park metadata, and modular view components for table, stats, progress, and map. Updates language files for new stats labels and enhances the update process to cache the full POTA parks CSV for richer features.
