feat: day batch — upload results surfaced as toasts (silent LoTW failures from the right-click send looked like nothing was sent); live selection count + Select all/Unselect all toggle in the grid toolbar; active filters bypass the row limit (all matches shown, 10k safety cap); NET Control: same right-click menu on worked-before + drag&drop roster<->on-air (drop on roster logs the QSO); compact mode restores previous window size/position; advanced-filter field renamed Station callsign; optional DXCC-style digital-mode grouping (Settings->General) for matrix badges + cluster colouring; changelog 0.20.9 entries (version NOT bumped)
