fix: use correct C-Gate config keys in addon install script

cgate-install.sh wrote CommandInterface.port and EventInterface.port to
C-GateConfig.txt, but C-Gate uses command-port and event-port. C-Gate
logged "Invalid key" warnings on every startup, and any user-customized
port was silently dropped — the addon kept using C-Gate's defaults
regardless of cgate_port / cgate_event_port.

Switch to the correct documented keys, anchor the grep checks with ^…=
so comment headers in C-GateConfig.txt don't produce false-positive
matches, and strip any legacy invalid keys left over from earlier
installs.

Bumps to 1.8.2.

+- **C-Gate config keys**: `cgate-install.sh` was writing `CommandInterface.port` and `EventInterface.port` into `C-GateConfig.txt`, but C-Gate uses `command-port` and `event-port`. C-Gate logged "Invalid key" warnings on every startup and any user-customized ports were silently dropped, so the addon kept using C-Gate defaults regardless of the configured `cgate_port` / `cgate_event_port` values. The script now writes the correct keys, anchors its grep checks with `^…=` so comment headers in `C-GateConfig.txt` don't produce false-positive matches, and strips any legacy invalid keys left over from earlier installs.
