Standardize filter widths per mode; fix FM web filter/deviation

- LSB/USB: 5.0k–1.0k (unchanged)
- DSB: split into own group 16k–2.4k (was sharing AM filters)
- CWL/CWU: 1.0k 800 600 500 400 250 150 100 50 25 (removed 750, added 150)
- AM/SAM: 20k–5.0k (new wider range)
- Web FNP FM: now shows NFM/FM only (11k/16k), matching desktop
- Fix SyncWebFilter: FM array out-of-bounds; FFMDeviation now set on web filter select
- VfoOverlay: DSB separated from SSB with own quick-select values
