chore: redesign about page as identity hero

Rebuild /about around an identity hero: instance branding with custom
profile fallbacks, a demo badge, and version/commit chips linked to the
GitHub release and commit. Dev builds show a plain version chip and hide
the unknown-commit chip.

Project links become an annotated directory (homepage, docs, API docs,
GitHub repo), followed by an MIT license note. The bird sprite gallery
moves out of the page, and the version/commit block leaves the settings
sidebar now that /about owns build info.
