fix(ci): SPDX identifier back to line 1, after the lockfile step

`gh actions-lock` inserts `# This workflow is managed by gh actions-lock.` at
line 1, which displaced the SPDX identifier moved there earlier in this branch.
The linter greps `head -1` only, so the header read as missing again.

Each file's OWN identifier is moved back to line 1 — nothing imposed. Files
already correct are untouched, and any file carrying two identifiers aborts the
change rather than guessing.
