* chore(ci): drop path filters and track github-actions in dependabot

Removing the doc-server/** and ci.yaml path filters from CI so the
build job runs on every PR. This lets us require the `build` status
check in branch protection without blocking PRs that only touch
top-level files (README, LICENSE, etc.) on a check that never reports.

Also adds the github-actions ecosystem to dependabot so the action
versions used by ci.yaml stay current.

* chore(deps): group github-actions dependabot updates into one PR

Per review feedback, group all github-actions ecosystem updates into a
single weekly PR to reduce noise from frequent minor action bumps.
