Rename about page source timestamp fields

Rename internal about page fields, DOM IDs, and test variables from build-time terminology to version-time terminology. The timestamp comes from Go's vcs.time metadata, which represents the source revision time rather than the compile time.

Testing:
- dev-scripts/git-hooks/pre-commit
- nix flake check
