Sens'it v2 has a totally different payload layout than Discovery v3:
- Bit order LSB→MSB (was MSB→LSB in v3)
- Mode in bits 0-2 (was bits 7-3 in v3)
- Battery split across bytes 0 & 1 (was 5 contiguous bits in v3)
- Temperature always sent (in T° MSB byte 1) even outside temp mode
Auto-detection uses byte 0 reserved bits: 0b110 = v3, otherwise = v2.
Frontend updated to render new fields: move_events, reed_events, fw_major/minor.
