Subject: [PATCH 1/3] Add non-persistent 'last_profile' variable for profile
 toggling (related to #767)

Add functionality to revert to the last used BLE profile via special index

This update introduces the ability to switch back to the previously active Bluetooth Low Energy (BLE) profile by passing index 255 to the profile selection function.
This feature facilitates quick toggling between two frequently used profiles, enhancing user convenience and efficiency in scenarios requiring regular switching between different BLE configurations.
