Dragan Spiridonov c442669ea8 fix(firmware): MGMT-only promiscuous filter to prevent SPI cache crash ...

The WiFi driver's wDev_ProcessFiq interrupt handler crashes with
LoadProhibited in cache_ll_l1_resume_icache when promiscuous mode
captures MGMT+DATA frames (100-500 interrupts/sec). The high interrupt
rate races with SPI flash cache operations, corrupting cache state.

Changes:
- Promiscuous filter: MGMT+DATA → MGMT-only (~10 Hz beacons)
- CSI config: disable htltf_en and stbc_htltf2_en (LLTF-only)

LLTF provides 64 subcarriers (HT20) — sufficient for presence,
breathing, and fall detection. The 10 Hz beacon rate eliminates
the SPI flash cache contention that caused the crash.

Verified on device 80:b5:4e:c1:be:b8:
- Before: LoadProhibited crash at ~1600-2400 callbacks (every ~70s)
- After: 2700+ callbacks over 4.7 minutes, zero crashes

Backtrace decode confirmed crash in ESP-IDF closed-source WiFi blob:
  _xt_lowint1 → wDev_ProcessFiq → spi_flash_restore_cache
  → cache_ll_l1_resume_icache → EXCVADDR=0x00000004 (NULL deref)
