feat: deep-link the logs link to the batch-filtered activity log on batch PRs

[JulianMaurin]

Batch PRs get their logs link back, pointing at the activity log with the
batch_pull filter (the batch's own lifecycle events) instead of the per-PR
event log. The link stays on closed batch PRs — the batch's event history is
the post-mortem trail. preset=Past1month widens the activity log's default
1-hour window, which would render empty for any batch older than an hour;
same convention as the dashboard's own queue → activity-log deep link.

MRGFY-7878

Test plan:

• npx jest (279 passing) — open batch PR (queue=batch_pr, logs=batch_pull),
  closed batch PR (logs only), non-batch PRs keep the per-PR event-log link.
• npx biome check — clean.

Pull request overview

This PR restores a “logs” link on merge-queue batch PRs, changing it to deep-link to the dashboard activity log filtered to the batch’s lifecycle events (batch_pull) and keeping that link available after the batch PR is closed for post-mortem inspection.

Changes:

• Update batch-aware link rendering so batch PRs use an activity-log deep link instead of omitting “logs”.
• Add getBatchActivityLogLink() to generate the activity-log URL with batch_pull and preset=Past1month.
• Update Jest coverage for open/closed batch PR link behavior and ensure non-batch PRs still use the per-PR event log link.
