Replace string-quoted station_id lists with comma-separated, integer-casted lists and harden SQL across awards models. This diff converts constructions like "'a','b'" to implode(',', array_map('intval', ...)) and uses $this->db->escape_str() for band/mode values and band lists to reduce injection/format issues. Added helper methods (addModeToQuery, addBandToQuery variants) to centralize mode/band filtering, parameterized time/mode/band queries in Gmdxsummer_model, and escaped band arrays when building IN() lists. Also added null/empty-checks for logbook arrays in several models and small refactors (e.g. VUCC addBandToQuery) to keep SQL building consistent.
Added collapsible filter panel with quick preset buttons, improved form layout, and a new statistics summary section showing WAJA progress and milestones. Prefecture names in the table are now clickable to view QSOs. Updated SQL queries in the Waja model to use the correct band key and improved SAT handling.
