feat: per-chat command toggle, listener name + toggle in bot tab

- Add commands_enabled field to TelegramChat (default off) with
  migration, gating command dispatch in both poller and webhook
- Show toggle switch per chat in bot tab for enabling/disabling commands
- Fix listener response to include bot name instead of just type
- Replace listener "Enabled" label + "Edit" link with toggle switch
  and crosslink to command-trackers page
