Squash-merges feature from PR #588 by @vcavichini. Dynamic <base href> injection + api() helper slash-stripping enables deploying hermes-webui behind a reverse proxy at any subpath without configuration. Also fixes pre-existing bug: api/upload was using location.origin instead of location.href (closes #596). Co-authored-by: vcavichini <vcavichini@users.noreply.github.com>
