Fix talkkonnect terminal initialization error in systemd service

PROBLEM:
- talkkonnect fails with "Cannot Initialize Terminal" error
- Service shows "Talkkonnect Terminated Abnormally" in logs
- Root cause: talkkonnect uses termbox-go which requires a TTY
- Systemd services don't provide TTY by default

SOLUTION:
- Added Environment="TERM=dumb" to systemd service
- Added StandardInput=null to prevent terminal initialization
- Both changes allow talkkonnect to run headless as a service

CHANGES:
- Updated install_kiosk_0.9.6-1.sh with the fix
- Created install_kiosk_0.9.6-2.sh (new version with fix)
- Added fix_talkkonnect_terminal.sh for quick patching of existing installations
