feat(ui): bulk-clear conversations, fold Start/Stop AI into the status dot

- Clear button beside Export deletes every conversation currently listed. It
  respects the search filter, so it doubles as "delete these matches"; the
  confirm text names which of the two is about to happen. Starts a fresh
  conversation id if the active one was among those deleted.
- The separate Start/Stop AI button is gone. The status dot was already
  colour-coding the same state and sitting right above it, so clicking it now
  toggles Ollama and the tooltip carries the phase text ("loading model…"),
  which is where the eye already is during the wait.
- Active nav/conversation items are marked with a blue left border and
  weighted text instead of a filled background, and the sidebar is wider so
  conversation titles stop truncating.
