fix(mdedit): root file tree at <project>/working/ even with no trailing slash

Browse source 
mdedit's loadServerDirectory derived its file-tree root by stripping
back to the last "/" in window.location.href. For a no-trailing-slash
canonical URL (<project>/working) that gave the wrong root: the parent
project directory rather than working/ itself. Visible symptom on
zddc-server's auto-served URLs after the recent dispatcher changes —
mdedit at /Project/working would show the project's archive, working,
staging, etc. all together instead of being sandboxed to working/.

Detect the directory-shaped URL by checking whether the last path
segment contains "." (file marker). No dot = directory; treat the
whole path as the root and append the trailing slash internally.

  /Project/working          → root /Project/working/  (was /Project/)
  /Project/working/x/y/     → root /Project/working/x/y/ (unchanged)
  /Project/x/mdedit.html    → root /Project/x/  (file URL; unchanged)
