The DOK award type (used for DLD award) now supports filtering by band,
mode, and other QSO fields. This allows creating award variants like:
- DLD on specific bands (80m, 40m, etc.)
- DLD on specific modes (CW, SSB, etc.)
- DLD with combined filters (e.g., 80m + CW)
Changes:
- Modified calculateDOKAwardProgress() to apply filters before processing
- Added example awards: dld-80m, dld-40m, dld-cw, dld-80m-cw
- Filter system uses existing applyFilters() function
