chore(lint): biome config + auto-fix sweep + translation hot-path quality fixes

- biome: enable unsafeParameterDecoratorsEnabled (NestJS @Body/@Query); ignore *.gen.ts; spec files override noExplicitAny
- translations: remove dictionary fallback DB write — was producing half-translated strings (e.g. "Body frame" → "Kaporta frame") that poisoned future lookups; now misses fall through to bootstrap script
- categories: add translateMany() to PCAT root/subgroup/parts insert paths (was only EMEX)
- auto-fix: organize imports, type-only imports, node: protocol on stdlib imports, and template-literal cleanups across 24 files

Drops lint count from 769 → 257; remaining are legacy noNonNullAssertion / noArrayIndexKey / useExhaustiveDependencies that need manual review.
