tui: streamline permission toggle command naming and add keyboard shortcut support

Rename 'Toggle autoaccept permissions' to 'Toggle permissions' for clarity
and move the command to the Agent category for better discoverability.
Add permission_auto_accept_toggle keybind to enable keyboard shortcut
toggling of auto-accept mode for permission requests.
