fix(header): make Asterion logo link to home

One-shot mu-plugin patches the Bricks heading 'hdrlgo' in template #25 to
add link.type='external' + link.url='/'. Idempotent — re-runs are safe.
Patches both _bricks_page_content_2 (JSON, source) and _bricks_page_header_2
(serialized PHP, mirrored by the REST bridge), so the change takes effect
immediately without re-running av-fix-template-meta.
