port upstream: AGC reset, autoadd max hops, noise floor EMA, fixes

Browse Source 
- AGC reset: proper warm sleep + Calibrate(ALL) + image recal for both
  SX126x and LR1110 (was cancel+restart / no-op respectively)
- Guard AGC reset against mid-receive (matches upstream RadioLib)
- Noise floor calibration: replace blocking 64-sample burst with
  single-sample EMA (alpha=1/8) per housekeeping tick — zero blocking,
  better temporal spread for real-world noise floor tracking
- Auto-add max hops: filter new contacts by hop count (NodePrefs,
  BaseChatMesh, CompanionMesh, ZephyrDataStore persistence)
- Fix CommonCLI memcmp("prefs", 4) → 5
