bug(s): default_mode locked causes input to not work

[dougg0k]

Issue description

When I set default_mode "locked" in the config.kdl input does not respond when unlocked.

1. Differently when no default_mode is set in the config. Ctrl + <g> always has the text Lock, regardless if locked or unlocked.
2. When the default_mode "locked" is set, text always show Unlock in both locked and unlocked mode. In both situations It's probably a small text bug.
3. When I set default_mode "locked", the background color of the bugged Unlock are in the opposite direciton, it shows when unlocked rather when locked.
4. As for the main issue, when default_mode are set to "locked", input works when terminal opens, but when you press Ctrl+g to unlock, the input stops working.

Minimal reproduction

1. Set default_mode "locked" in the config.kdl
2. Open terminal with zellij
3. Try typing while unlocked and locked
