* fix(invoice-inbox): stub DOM globals so pdfjs text extraction works on Vercel
pdfjs-dist's legacy build references DOMMatrix/ImageData/Path2D at module
load. On Vercel's Node runtime those globals don't exist, so the dynamic
import threw "DOMMatrix is not defined" before getDocument() ran — every
inbox item came back with empty extracted_data. We only call
getTextContent (no rendering), so empty-class stubs are sufficient.
Also mark pdfjs-dist as a server external package so Next.js doesn't try
to bundle it (the bundling step pulls in @napi-rs/canvas references that
aren't installed and fails silently with the same downstream error).

* refactor(invoice-inbox): hoist DOM stubs to module scope
Per Greptile review on #407: stubs run once at module load instead of
per-call. Same effect, clearer intent. Wrapped in a block to scope the
local variable.
