* fix(sonarr): unblock DELETE_SHOW_IF_EMPTY and surface cleanup skips (#2763)

DELETE_SHOW_IF_EMPTY silently bailed when Seerr was configured but
the show was not tracked in Seerr, and when every remaining Seerr
request was already COMPLETED. hasRemainingSeasonRequests returned
undefined for missing mediaInfo the same way it does for real
communication errors, and the outer request filter kept COMPLETED
requests in scope so their seasons were still scanned.

- Treat a Seerr response with no mediaInfo as "nothing to protect"
  (returns false); keep undefined strictly for communication errors.
- Exclude COMPLETED requests at the outer filter so fulfilled
  history does not block deletion.
- Add a debug log at every bail path in deleteShowIfEmpty and
  unmonitorShowIfEmptyAndEnded so users can see why a show was kept.
- Add spec coverage for: untracked show, empty requests,
  communication failure, Seerr state unknown from the handler, and
  files-still-remain.

The PR #2618 design intent (Seerr is the authority when configured,
ended shows included) is preserved.

Fixes #2757

* Add token for GitHub authentication in workflow

Added token usage for authentication in docs drift workflow.

* ci(docs-drift): remove create_pr step and input

The draft PR was empty scaffolding — the drift issue already carries
the same report and is the canonical tracking surface. Drop the unused
create_pr dispatch input and the push/PR creation step.

* ci(stale): use GITHUB_TOKEN for stale-issue bot

The job already requests issues: write, which GITHUB_TOKEN satisfies —
no need for the ACTIONS_TOKEN PAT. Dropping this removes the last
workflow reference to ACTIONS_TOKEN.
