`getEndpointUrls()` resolved relative endpoint paths (e.g. `/media`) using
`getUrl(request)`, which returns `http://` because Express sees HTTP from nginx
without trust proxy. This produced `http://blog.giersig.eu/media` as the
endpoint attribute in the file-input component, causing Safari to block the
fetch as mixed content ('Load failed').
Fix: prefer `application.url` (the configured HTTPS base URL) over
`getUrl(request)` when resolving relative endpoint paths.
