Fix MICR font path, date import, PDF button bug; clean up config; add TODO markers

- Hardcode GnuMICR.otf path in pdfService.js; remove MICR_FONT_PATH env var
- Fix normalizeDate to handle MM/DD/YY (2-digit year) and return null on no match
- Fix generatePdf button DOM bug: update span directly instead of overwriting textContent
- Remove .env.example and NTFY_URL from docker-compose (app has no required config)
- Remove redundant fonts volume mount from docker-compose (fonts bundled in image)
- Mark MVP TODO items complete; add // TODO comments in source for post-MVP features
- Update README: correct slot height, remove stale env var docs
