Add diagnostic script to check talkkonnect terminal fix status

Created check_talkkonnect_fix.sh to verify if the terminal initialization
fix has been applied to the talkkonnect systemd service. This script checks
for the presence of:
- Environment="TERM=dumb"
- StandardInput=null

These settings are required to prevent the "Cannot Initialize Terminal" error
when talkkonnect runs as a systemd service without a TTY.
