docs: Update documentation with new modes, screenshots, and carousel UI

Browse Source 
Add VDL2 to README, FEATURES.md, and USAGE.md. Add missing usage guides
for ACARS, WebSDR, ISS SSTV, HF SSTV, TSCM, Spy Stations, and Offline
Mode. Add ISS SSTV section to FEATURES.md. Add 7 new screenshots to
GitHub Pages (Spy Stations, GPS, WebSDR, VDL2, Weather Satellite,
Satellite Tracker, ISS SSTV). Redesign features section as a filterable
carousel with category tabs, SVG icons, and scroll indicators.
