Merge Risk: 🔵 Low · up to Malformed font configuration can prevent PDF generation, and a failed browser download can appear successful. These are bounded issues, but both should be fixed before relying on the new toolkit. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Add src/utils/pdf: a React-agnostic PDF toolkit built on pdfmake. Pure
templates (data, { font }) => docDefinition run through createDocument,
which resolves the font, builds the document, and returns download/open/
print/getBlob/getBase64. Ships no font or image: resolveFont and
imageDataUrl fetch + base64 a consumer-provided brand font/logo (pdfmake's
browser build can't load either by URL) and fall back to Helvetica.
field and badge are shared docDefinition node builders; downloadBlob
saves via a light-DOM anchor so it works from inside a shadow root.
pdfmake is an optional peer: the toolkit never imports it, the consumer
injects its own instance, so there is one VFS and one singleton owner.

Review comments at @src/utils/pdf/download-blob.js:
- Around line 1-36: Update the catch block in downloadBlob to rethrow the caught
error after logging it, so failures from URL.createObjectURL,
document.body.appendChild, or a.click() propagate to createDocument().download()
and trigger its onError handling.
Review comments at @src/utils/pdf/resolve-font.js:
- Around line 59-62: Update resolveFont to verify that font.fonts contains
font.family before registering the pre-baked container or returning that family;
when it does not, return the existing Helvetica fallback, matching the URL
failure behavior.

downloadBlob only logged a failed download, so createDocument().download() resolved and onError never ran. downloadBlob rethrows the error after logging it.
resolveFont registered a pre-baked container even when its fonts did not define the family, and pdfmake failed later while building the file. Such a container falls back to Helvetica, like a font URL that fails to load.

Ports the pdfmake PDF toolkit (
src/utils/pdf) to the 5.x line. Same surface as the 4.x PR:createDocument,resolveFont,imageDataUrl,downloadBlob,field,badge;pdfmakeas an optional peer.Why: react-pdf renders through react-reconciler. React 19 commits the reconciler container asynchronously, but react-pdf reads
container.document.propssynchronously right afterupdateContainer— so under React 19 it reads null and throws (Cannot read properties of null (reading 'props'), upstream diegomura/react-pdf#3223); under React 17/18 the commit was synchronous and never raced. Our stack spans React 17/18 (legacy widgets) and React 19 (the Next event site), so PDF generation broke on React 19. pdfmake has no reconciler, so it sidesteps this entirely.Summary by CodeRabbit
