Changes:
- Add SCRIPT_DIR variable for locating companion scripts
- Update addon_talkkonnect_intercom() to launch setup_intercom.sh
- Replace 134 lines of duplicate code with 30-line integration
- Update INTERCOM_README.md with clear usage instructions
Benefits:
- Single source of truth for intercom functionality
- Easier maintenance (update only setup_intercom.sh)
- Cleaner separation: install_kiosk handles UBK, setup_intercom handles intercom
- Both scripts work standalone or together automatically
Usage:
- Option 1: Run install_kiosk_0.9.6.sh → Addons → Intercom (option 4)
- Option 2: Run setup_intercom.sh directly
- Both scripts must be in same directory (automatic when cloning repo)
