Anchor PDF payment card to footer and size QR to text height

Move the payment info card (account number, IBAN, SWIFT) to the
bottom of the invoice page so it sits flush with the footer, and
size the QR code to match the combined height of the three payment
lines instead of a fixed size.

+## CI/CD
+
+On every push to `main`, GitHub Actions (`.github/workflows/ci-cd.yml`) runs the
+test suite, then builds and publishes a dev image to the GitHub Container
+Registry:
+
+```
+ghcr.io/odweta/fakturovac:dev
+```
+
+A commit-pinned tag (`ghcr.io/odweta/fakturovac:dev-<short-sha>`) is published
+alongside `:dev` for traceability. Pull requests only run the test job.
+
+To pull and run the latest dev image in a testing environment:
+
+```bash
+docker login ghcr.io -u <your-github-username>   # only needed if the package is private
+docker pull ghcr.io/odweta/fakturovac:dev
+docker run -d -p 3001:3001 \
+  -e DATABASE_URL=postgres://fakturovac:fakturovac@<db-host>:5432/fakturovac \
+  -e NODE_ENV=production \
+  ghcr.io/odweta/fakturovac:dev
+```
+
+The package's visibility (public/private) is managed under the repository's
+**Packages** settings on GitHub; no extra secrets are required since the
+workflow authenticates with the built-in `GITHUB_TOKEN`.
