chore: make lint and format validation commands non-mutating

`format-lint` and the web app's `lint` both ran `biome check --write`, so
the commands CONTRIBUTING points at as pre-PR validation rewrote the
working tree instead of reporting on it.

Drop `--write` from both and move the auto-fixing behaviour to explicit
`format-lint:fix` / `lint:fix` scripts. CONTRIBUTING and CLAUDE.md are
updated to name the read-only commands, and the auto-fix CI workflow now
invokes `format-lint:fix`, since it relies on the fixes actually being
applied.

Fixes #1448
