chore: resolve merge conflicts with origin/main

- tsconfig.json: use main's ES2022 target with decorators support
- jest.config.js: merge both test roots (src/__tests__ and tests/)
- package.json: union of both dependency sets
- src/index.ts: keep auth/admin routes + add redis health/metrics endpoints from main
- package-lock.json: regenerated after dependency merge
