chore(instrumentation): skip initialization in CI environment

- Added checks to skip database migrations, price seeding, and queue scheduling when running in a CI environment.
- Updated AsyncTaskManager to avoid unnecessary initialization during CI/build phases.
- Implemented lazy loading for Redis client to prevent connection attempts during CI/build.
