Adds a cross-cutting "文件与图片引用" section to docs/api/README.md covering the
parameter, the deployment default, the endpoints it applies to, and the two
caveats that matter in practice: it needs APP_EXTERNAL_URL (or a publicly
reachable storage backend) to produce a link at all, and the links it produces
are time-limited but anonymously readable.
Also annotates the affected endpoints for Swagger and refreshes the generated
files for those parameters only, leaving unrelated drift in the committed
swagger output alone.
