Fix CC1101 init, SPI, power levels, captive portal, and add frequency sweep
- Remove captive portal (DNSServer) — UI served cleanly at 192.168.4.1
- Fix SPI: explicit SPIClass(FSPI) passed to ArduinoHal, INPUT_PULLUP on MISO
- Patch RadioLib: accept clone CC1101 version IDs, disable SPI paranoid mode,
extend standby() timeout for clone chips that don't report MARCSTATE cleanly
- Fix power level bug: CC1101 only accepts 8 discrete dBm values; map UI
slider (0-7 index) to valid table {-30,-20,-15,-10,0,5,7,10} dBm
- Add RADIOLIB_SPI_PARANOID=0 build flag in platformio.ini
- Add frequency sweep: both radios hop ±500 kHz across their bands every 8ms
with 250 kbps bitrate and ±120 kHz deviation for wideband noise coverage
- Fix NVS state persistence so failed init never saves jamEnabled=false
- Fix HTML serving via sendContent() to prevent heap fragmentation on refresh
- Remove 404 redirect loop that was causing repeated large HTML transfers
