feat(ook): add timing presets, RSSI, bit-order suggest, pattern filter, TSCM link

- Timing presets: five quick-fill buttons (300/600, 300/900, 400/800, 500/1500, 500 MC)
  that populate all six pulse-timing fields at once — maps to CTF flag timing profiles
- RSSI per frame: add -M level to rtl_433 command; parse snr/rssi/level from JSON;
  display dB SNR inline with each frame; include rssi_db column in CSV export
- Auto bit-order suggest: "Suggest" button counts printable chars across all stored
  frames for MSB vs LSB, selects the winner, shows count — no decoder restart needed
- Pattern filter: live hex/ASCII filter input above the frame log; hides non-matching
  frames and highlights matches in green; respects current bit order
- TSCM integration: "Decode (OOK)" button in RF signal device details panel switches
  to OOK mode and pre-fills frequency — frontend-only, no backend changes needed
