Add tag input to workflow_dispatch for manual releases

When manually triggering the release workflow, a tag input is now
required (e.g. v0.23.0). All checkout steps use this tag as the ref,
and Docker metadata uses it for proper image tagging. When triggered
by a tag push, the behavior is unchanged (falls back to github.ref).
