Lora settings expansion and validation logic improvement (#9878)

* Enhance LoRa configuration with modem presets and validation logic

* Rename bootstrapLoRaConfigFromPreset tests to validateModemConfig for clarity and consistency

* additional tidy-ups to the validateModemConfig - still fundamentally broken at this point

* Enhance region validation by adding numPresets to RegionInfo and implementing validateRegionConfig in RadioInterface

* Add validation for modem configuration in applyModemConfig

* Fix region unset handling and improve modem config validation in handleSetConfig

* Refactor LoRa configuration validation methods and introduce clamping method for invalid settings

* Update handleSetConfig to use fromOthers parameter to either correct or reject invalid settings

* Fix some of the copilot review comments for LoRa configuration validation and clamping methods; add tests for region and preset handling

* Redid the slot default checking and calculation. Should resolve the outstanding comments.

* Add bandwidth calculation for LoRa modem preset fallback in clampConfigLora

* Remove unused preset name variable in validateConfigLora and fix default frequency slot check in applyModemConfig

* update tests for region handling

* Got the synthetic colleague to add mock service for testing

* Flash savings... hopefully

* Refactor modem preset handling to use sentinel values and improve default preset retrieval

* Refactor region handling to use profile structures for modem presets and channel calculations

* added comments for clarity on parameters

* Add shadow table tests and validateConfigLora enhancements for region presets

* Add isFromUs tests for preset validation in AdminModule

* Respond to copilot github review

* address copilot comments

* address null poointers

* fix build errors

* Fix the fix, undo the silly suggestions from synthetic reviewer.

* we all float here

* Fix include path for AdminModule in test_main.cpp

* Potential fix for pull request finding
