chore: add owner SPDX header to all .rs (satisfy licence hook) + axial test rename

The pre-commit licence enforcer requires BOTH SPDX-License-Identifier: MPL-2.0
AND the owner string 'Jonathan D.A. Jewell <j.d.a.jewell@open.ac.uk>' on every
staged source file, but NO .rs file carried the owner line -- so any edit to a
.rs file was blocked by the hook (a latent repo-wide gap). Inserts the
SPDX-FileCopyrightText owner line on line 2 of all 91 tracked .rs files (each
already had SPDX-License-Identifier on line 1). Also renames the cosmetic
'audience.md' temp filename in the axial test to 'axial.md', completing the
audience->axial sweep.

Comment-only changes plus one test-string rename; cargo check --all-targets passes.
