<#
.SYNOPSIS
    Fixes missing Bluetooth icon, device, or service post Windows update.
.DESCRIPTION
    Re-initializes Bluetooth subsystem components:
    - Sets Bluetooth Support Service (bthserv) to Automatic and starts it
    - Configures Bluetooth Audio Gateway Service (BTAGService)
    - Re-enables disabled Bluetooth PnP hardware radios
    - Initiates device manager rescan
    Idempotent and safe to run multiple times.
