fix(ci): use public rust:1.82-bookworm image instead of custom image

Replace custom CI image with public rust image to fix workflow failures.
Add Node.js installation step for rust-fmt-check job.

The custom image (gitea.tftsr.com:3000/sarman/trcaa-linux-amd64:rust1.88-node22)
needs to be built via build-images workflow first.
