* feat: add adaptive polling intervals to WebServer
Replace fixed 5ms polling with adaptive intervals based on HTTP activity:
- 50ms during active periods (first 5 seconds after request)
- 200ms during medium activity (5-30 seconds)
- 1000ms during idle periods (30+ seconds)
Reduces CPU usage significantly during idle periods while maintaining
responsiveness when handling HTTP requests.
* Fix integer overflow and magic numbers in WebServer
- Handle millis() overflow in getAdaptiveInterval()
- Replace magic numbers with named constants
- Improve code readability and maintainability
* Fix excluded modules configuration handling
- Add excluded_modules flags in getDeviceMetadata() for MQTT, PAXCOUNTER, STOREFORWARD, RANGETEST, NEIGHBORINFO
- Add conditional compilation guards in AdminModule for RANGETEST, AUDIO, PAXCOUNTER, STOREFORWARD, EXTNOTIF, DETECTIONSENSOR, AMBIENTLIGHTING
- Add skip logic in PhoneAPI for excluded modules during config enumeration
- Add conditional has_* flags in NodeDB only for included modules
Fixes issue where excluded modules still appeared in client applications and sometimes caused PAYLOADVARIANT_NOT_SET errors.
* Fix excluded modules issues and refactor code
- Restore original PAXCOUNTER logic: only exclude on non-ESP32 platforms due to memory constraints
- Fix has_store_forward flag to be conditionally compiled based on MESHTASTIC_EXCLUDE_STOREFORWARD
- Refactor PhoneAPI module config skipping logic to use helper function skipExcludedModuleConfig()
- Reduce code duplication in PhoneAPI by extracting common skip logic
This addresses the three issues identified in the code review:
1. PAXCOUNTER memory impact on non-ESP32 devices
2. Unconditional has_store_forward flag setting
3. Duplicated state management logic across multiple #else blocks
* Fix ambient lighting module exclusion in PhoneAPI and AdminModule
- Add conditional compilation guards for ambient lighting in PhoneAPI.cpp
- Replace old HAS_RGB_LED logic with MESHTASTIC_EXCLUDE_AMBIENTLIGHTING check in AdminModule.cpp
- Ensure ambient lighting module is properly excluded when MESHTASTIC_EXCLUDE_AMBIENTLIGHTING=1
