content: split by concern, every path still content::x

Browse Source 
content.rs was 2,373 lines doing five jobs. It is now a directory:
mod.rs keeps the types and the resolution rules (router, refs,
reachability, build_questions) and the tests; gitea.rs loads from
Gitea and watches for reload, through crate::http; validate.rs holds
the checks a repo must pass; markdown.rs the inline markdown;
handlers.rs the Axum routes. Each submodule is re-exported from
content, so no caller changes. The loader module is server-only and
gated as such. No behaviour change; 65 unit tests unchanged and green.
