CI: craft-fonts run uses the Test step's exact build again (Linux runner out of disk since #800) (#955)

#800 narrowed the craft-fonts test run to -p photocraft-text -p photocraft-ui-egui. A
different package and feature selection resolves a different feature set (no
--features heif), so cargo recompiled the whole dependency graph into the same
target dir on top of the Test step's build, and test (ubuntu-latest) ran out of
disk (No space left on device, linker bus error) on main and every PR.

Back to cargo test --workspace --locked --features heif, which reuses the Test
step's artifacts and rebuilds only the crates that read CRAFT_FONTS_DIR. The comment
says why the selection must match.
