Subject: [PATCH] fix(archive): scope to URL subpath when auto-served at a
 no-slash directory URL
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When zddc-server auto-serves the archive tool at a sub-folder URL (e.g.
/Project-1/Archive/PartyA/Issued, no trailing slash, no archive.html
filename), the tool's autoConnectHttpSource was stripping the last URL
segment under the assumption it was a filename. Result: archive scanned
the PARENT directory (/PartyA/) instead of /Issued/, showing
transmittals from sibling folders the user hadn't asked for.

Fix: detect the URL shape before deciding what the scan root is.

  - Trailing slash → URL is already a directory; use as-is.
  - Last segment has a dot → filename (archive.html); strip to parent.
  - Last segment has no dot → bare directory name (auto-served URL);
    treat the entire path as the scan root and append '/'.

Now /Project-1/Archive/PartyA/Issued shows only the transmittal folders
inside Issued/ — the locally-mounted-folder experience the user expected.
