fix: self-heal BootReceiver on startup to survive aggressive OS pruning

Some smart display and TV OS implementations silently place background broadcast
receivers into a disabledComponents list after reboot. This breaks the standard
BOOT_COMPLETED broadcast and prevents the launcher service from starting unattended
after hard power cuts.

Added an initialization check in LauncherService.onCreate() that dynamically re-enables
BootReceiver via PackageManager if it was tampered with by the OS, ensuring the
web server will restart successfully on the next boot cycle.

Ported fix from PR #17 (credit: @andornaut).
