ci(workflow): drop the PAT - use the built-in token per repo

The monitor used to run on the fork and open PRs against upstream,
which structurally requires a cross-repo PAT. Two changes remove it:

- PRs are created in whichever repo the workflow runs in
  (GITHUB_REPOSITORY), so the built-in github.token covers both push
  and pr create - same pattern as upstream's
  auto_update_price_and_context_window workflow
- the job guard flips: upstream owns the merged schedule
  (github.repository == BerriAI/litellm), the fork stays dispatch-only,
  so the two never race on the same base

The script bootstrap from the fork branch stays until #38950 lands
upstream. DBX_MONITOR_TOKEN secret is no longer referenced.
