fix(ci): pin third-party actions to full commit SHAs

The account's Actions policy requires a full-length SHA ref. A tag or branch ref is refused at
startup — startup_failure, no jobs, "this workflow graph cannot be shown" — so these workflows
could not run at all. This resolves each ref to the commit it currently points at and records the
ref in a trailing comment, e.g. actions/checkout@<sha> # v4.

dtolnay/rust-toolchain takes its toolchain from the ref itself, so those steps also gained an
explicit with: toolchain: input; without it, a SHA ref would silently lose the channel.

No behaviour is intended to change beyond the pins.

The email-notification workflow can be rejected before it starts because its lockfile still describes an older action release. Regenerate and commit the action lockfile before merging.

Synchronise the pinned version metadata.

The workflow uses the v0.3.0 commit, but .github/workflows/actions.lock still records v0.2.0. The estate enforces this lockfile, so stale metadata can cause gh actions-lock validation to reject the workflow before any step runs.

Run gh actions-lock to update the lockfile to v0.3.0. Retain the # v0.3.0 trailing version comment and the existing NOSONAR note on the SHA pin.
