Approval mode of automations in the list; Telegram switch per chat

- Automations: the approval mode is a selection in the list; PATCH /jobs/{id}
  writes permission_mode into the job file's frontmatter (rest of the file
  unchanged, invalid modes rejected). "Allow everything" lets nightly runs work
  without waiting for approvals via Telegram until the timeout.
- Session.telegram_quiet: approvals and questions of a chat (and its subagents)
  are not sent to Telegram; the chat open in Telegram always reports. Toggle in
  the chat's ⋯ menu when a bot is paired. New chats from the web UI and
  automation runs start quiet; chats started from Telegram and existing chats
  keep reporting.
