Subject: [PATCH 1/2] feat(seer): Print Explorer URL after night shift trigger
 script runs

The trigger-night-shift script now outputs a clickable Explorer URL
after a run completes, making it easy to jump straight to the triage
session for debugging. Falls back to printing the raw run ID if the
URL prefix isn't configured.

To support this, run_night_shift_for_org now returns the agent_run_id.
The return value is ignored when dispatched via Celery.

Subject: [PATCH 2/2] fix(seer): Use explicit return None for mypy strictness

Bare `return` in `run_night_shift_for_org` (annotated `-> int | None`)
tripped mypy's `[return-value]` check in CI. Make the early exits
explicit with `return None`.
