fix: apply consistent-type-imports across API codebase (728 lint errors)

- Convert `import type { X }` to `import { type X }` (inline-type-imports style)
- Suppress consistent-type-imports for `typeof import()` in instrument.ts
- Includes uncommitted agent work: metrics module, redis caching, audit logs,
  saved searches, circuit breaker, rate limiting, and admin enhancements
