Pasting an image while the markdown editor was focused left it stuck on
ProseMirror's inline "uploading" placeholder instead of going to the
attachment strip. The capture-phase paste interceptor bailed before it
could redirect the file because:
- pasted images usually surface only through `clipboardData.items`
(`getAsFile`), with `clipboardData.files` left empty, and
- image pastes often advertise an *empty* `text/plain` entry, which the
old `types.includes('text/plain')` check mistook for a text paste.
Read files from `items` (falling back to `files`), and gate on the actual
text payload rather than the advertised type, so real text pastes
(Excel/Word renditions) still paste as text while pure image pastes
become attachments.

Notes
CORS for desktop app
In dev: each renderer process has its own localhost port. The renderer process passes this in the Origin header for requests, and expects appropriate ACAO headers in the response.
In packaged app: the renderer process does not include Origin header, so expects no extra ACAO headers from the server, otherwise the client would fail to accept responses.
