Make Docker bind mounts actually work; refresh homepage feature grid

App/, cache/, uploads/, and data/ are now bind-mounted by default, so
docker-entrypoint.sh seeds an empty App/ from a build-time backup and
re-chowns the mounted paths to http:http on every start (a bind mount
doesn't inherit a named volume's ownership or get seeded from the image
the way COPY does). Also fixes AllowOverride never actually being
enabled (the sed pattern didn't account for httpd.conf's indentation,
so only DirectoryIndex-served routes worked) and pins Apache/PHP/SQLite
to a dated Arch Linux Archive snapshot for reproducible builds.

Homepage's feature grid was six cards behind what's actually shipped;
brought it in line with the features blog post.

 ## Documentation
 
 The full framework documentation lives inside the framework itself, at `/admin/docs` on any running instance — so it travels with the code, no internet connection needed. That's the canonical reference for everything: requirements, running locally, deploying on Apache or Docker, starting a new project, updating the framework, adding a page, routing, sidecars, libraries, database, session, content index, XML sitemap, RSS feeds, layouts, static caching, SEO, Matomo analytics, admin authentication, access control, draft pages, media manager, styling, and project layout.
