perf: cut biome lint from 25s to 1s and fix pre-existing lint failures

Exclude generated drizzle-kit snapshot artifacts from formatting checks (drizzle/drafts/meta), which made biome scan a 360KB generated JSON for 23s. Fix the pre-existing lint errors in error-monitor, article-form and the admin-search-permissions mock so pnpm biome:lint is green in CI.
