Fix CI failures: biome format, audit command, dependency review

- Lint job: replace `biome lint` + `biome format --check` with
  single `biome check` (Biome v2 removed --check flag)
- Audit job: replace `bun pm audit` with `npx audit-ci --high`
  (bun removed audit subcommand)
- Dependency review: add continue-on-error (needs Advanced Security)
- Test job: remove unnecessary build step before tests
