Upstream 1.7.2 prefixes most hand-written URLs with basePath via apiFetch /
withBasePath, but four subpath-relevant spots were missed:
- host-bridge: the sandbox iframe src was a bare "/plugin-sandbox" -> 404
under NEXT_PUBLIC_BASE_PATH, breaking all plugins. Wrap in withBasePath.
- host-api doHttpPost: the same-origin /api/* plugin proxy used raw fetch on
url.pathname -> 404 under a subpath. Route it through apiFetch.
- admin branding preview <img>: unprefixed src -> broken thumbnail.
- (sandbox) layout: drop the Geist font + globals.css imports. The sandbox
runs with an opaque origin, so those assets are CORS-blocked; the plugin
bundle and all host API calls travel over the postMessage bridge, so no
same-origin asset fetch happens there.
The quick-reply box built its body with appendPlainTextSignature, which runs
the identity's HTML signature through htmlToPlainText, and sent a text-only
message (htmlBody was undefined). A formatted signature (e.g. <strong>…) was
therefore flattened to plain text in the sent mail, even though it previewed
correctly in the identity editor. The full composer already builds an HTML
signature block; quick reply did not.
Add an appendHtmlSignature helper (mirrors the composer's send-time block) and,
when the sending identity has an HTML signature, send a matching HTML body from
handleQuickReply so the markup is preserved. Text-only identities keep the
plain-text-only behavior.

The Files page UI sat at 0% throughout an upload because uploadBlob()
uses fetch(), which does not surface upload progress events. The store
set loaded=0 before the call and loaded=file.size after it, so users
saw the progress bar jump from 0% straight to 100% on completion --
and on slow connections (or large files) it appeared frozen.
Switch uploadBlob() to XHR when the caller passes onProgress or an
AbortSignal, so progress events from xhr.upload.onprogress can drive
the UI. Callers that don't pass either keep the fetch path so we
preserve the existing 401-retry behaviour in authenticatedFetch().
Wire the file store to pass both onProgress (updates uploadProgress
in real time) and the existing AbortController's signal (so cancel
now actually aborts the network request, not just the post-upload
createFileNode step).
uploadBlob() is part of IJMAPClient so the signature change is also
applied to the demo client (synthesises 0% then 100%).
