Automation editor with graphical schedule and assistant; movable chat list groups

Automations
- Job files hold only the instructions; name, schedule, mode, model, approval
  mode and time limit are settings in the database (jobs.settings). Existing
  files are adopted on start-up (frontmatter into the database and removed from
  the file); plain Markdown files registered later get default settings and stay
  switched off until scheduled.
- New automation: name, project and a starting point (blank example structure or
  a template) create .codecraft/jobs/<name>.md and open the editor: settings with
  a graphical cron builder (next runs in server time via /jobs/schedule), the
  instructions in the Markdown editor and an assistant chat
  (POST /jobs/{id}/assistant) whose model edits the file; the editor reloads it
  after each turn and warns about conflicts with unsaved edits.
- The schedule tool writes prompt-only files with settings.

Chat list
- Folders and projects keep a user-defined order and can be pinned (drag and
  drop, or the group's menu), stored per user via /account/sidebar. A new
  message moves the chat to the top of its group, no longer the project itself.
