Add an explicit permissions block to every workflow that relied on the
repository default. Entry points that only call reusable workflows get
permissions: {} and grant each call what the called workflow needs:
contents: read for the bundle and docker builds, contents: write for the
release, nothing for the admin-console dispatch (it uses its own token).
Workflows that check out code get contents: read; the commit checker
also gets pull-requests: read to list the PR commits.

Set persist-credentials: false on every actions/checkout step, so the
job token is not left in .git/config for the rest of the job. No step
after checkout pushes or fetches with it. The only authenticated operation,
gh release in release.yml, uses GH_TOKEN.

The MCP workflow was named "MCP CI" while every other tests-*.yml
workflow uses the "CI: <Component>" pattern. Rename it to "CI: MCP"
for consistency in the GitHub Actions listing.
