deploy: PDF parse DOMMatrix polyfill + email send pacing

[RikepilB]

Promotes main to master for production deploy.

Changes

• fix(resume): polyfill DOMMatrix/ImageData/Path2D from @napi-rs/canvas before pdf-parse loads — fixes ReferenceError: DOMMatrix is not defined that failed every PDF parse on Vercel (PR fix(resume): polyfill canvas DOM globals for PDF parsing on Vercel #93)
• fix(emails): pace inline admin fan-out sends by 300ms to stay under Resend's 5 req/s limit

Test plan

• CI green on PR fix(resume): polyfill canvas DOM globals for PDF parsing on Vercel #93 (lint, typecheck, test, build)
• Post-deploy: submit fresh PDF application on prod, verify parsingStatus COMPLETED
• Post-deploy: verify EmailLog has no 429 errors

📝 Walkthrough

Walkthrough

This PR adds a Canvas polyfill to enable server-side PDF text extraction and implements pacing for admin notification email dispatches. The canvas dependency polyfills missing DOM globals in Node environments, while the dispatch change throttles consecutive email sends with 300ms inter-send delays.

Changes

PDF Text Extraction Polyfill

Layer / File(s)	Summary
Canvas dependency and DOM globals polyfill package.json, src/lib/resume/extractText.ts	Added @napi-rs/canvas dependency and implemented ensurePdfDomGlobals() helper that lazily loads canvas APIs and assigns DOMMatrix, ImageData, and Path2D to globalThis with graceful failure handling.
PDF parse initialization with polyfill src/lib/resume/extractText.ts	Updated loadPdfParse() to call ensurePdfDomGlobals() before importing pdf-parse, ensuring DOM globals are available for server-side text extraction.

Admin Email Dispatch Pacing

Layer / File(s)	Summary
Email dispatch pacing with test helpers src/server/jobs/dispatch.ts, src/server/jobs/dispatch.test.ts	Changed dispatchAdminNotificationEmails to insert 300ms delays between consecutive inline email sends, added flushPacedFanOut() test helper to wait for paced work completion, and updated inline-mode tests to use the new timing-aware flush approach.
