Update admin commands to include channelpause functionality

- Added `channelpause` and `channelresume` commands to the admin commands list in configuration files, allowing admins to pause or resume bot responses on public channels via DM.
- Updated documentation to reflect the new command functionality and its implications for channel responses.
- Modified validation and message handling to incorporate the new channel response control feature.
