Update/add MCB sensors and thresholds

[pawagh1]

This update refines the sensor_service.json configuration for the MCB to align with the latest threshold definitions and to remove deprecated or hidden sensor entries no longer in use.

Key highlights of this update:

1. Removal of Deprecated Sensors:
   The following sensors were identified as obsolete and have been removed to maintain a clean and relevant sensor configuration:

   • MCB_P12V_BP_ADC0_A
   • MCB_P12V_BP_ADC0_B

2. Threshold Definition Updates:
   Threshold parameters for existing sensors have been refreshed to the latest defined values. This includes updates to:

   • upperCriticalVal and lowerCriticalVal
   • Newly added maxAlarmVal and minAlarmVal where applicable
     These changes ensure accurate alarm triggering and improved monitoring reliability within expected operational ranges.

No new sensors were added as part of this update. Existing sensor attributes such as slotPath, sysfsPath, pmUnitName, and type remain consistent with previous configurations.

Test Plan:

1. Confirm all sensors are enabled and reporting valid readings.
2. Verify all sensor values are within the defined threshold limits.
3. Ensure removed sensors (MCB_P12V_BP_ADC0_A, MCB_P12V_BP_ADC0_B) are not listed.
