8384659608 fix: apply all LoRa config changes live without rebooting (#9962)
* fix: apply all LoRa config changes live without rebooting

All LoRa radio settings (SF, BW, CR, frequency, power, preset,
sx126x_rx_boosted_gain) now apply immediately via reconfigure()
without requiring a node reboot.

- AdminModule: requiresReboot = false for all LoRa config changes;
  LoRa changes were already handled by the configChanged observer
  calling reconfigure() but the reboot flag was set unnecessarily
- AdminModule: validate LORA_24 region against radio hardware at
  config time; reject with BAD_REQUEST if hardware lacks 2.4 GHz
  capability (wideLora() returns false or no radio instance)
- SX126xInterface/LR11x0Interface: apply sx126x_rx_boosted_gain in
  reconfigure(); register 0x08AC is writable in STDBY mode (SX1261/2
  datasheet §9.6); retention registers written so setting survives
  warm-sleep cycles; log warning on setter failure
- DebugRenderer: show BW/SF/CR on debug screen when custom modem is
  active instead of the preset name
- DisplayFormatters: clarify comment on getModemPresetDisplayName

* fix: remove redundant reboot after LoRa config changes in on-device menus

Region, frequency slot, and radio preset pickers in MenuHandler all
called reloadConfig() then immediately set rebootAtMsec. reloadConfig()
already fires the configChanged observer which calls reconfigure(), so
the forced reboot was unnecessary — same rationale as the parent commit.

* fix: guard LORA_24 region selection against hardware capability in on-device menu

Without a reboot, reconfigure() now applies region changes directly.
Previously getRadio() caught the LORA_24-on-sub-GHz mismatch post-reboot
and reverted to UNSET — that safety net is gone. Add an explicit wideLora()
check in LoraRegionPicker so sub-GHz-only hardware silently ignores LORA_24
selection instead of attempting a live reconfigure with an invalid frequency.
