refactor: switch from monorepo to independent frontend and backend setups

- Removed root pnpm-lock.yaml and pnpm-workspace.yaml
- Frontend and backend now manage their own dependencies independently
- Updated CI workflows to run pnpm install in specific directories
- Updated workflow triggers to use local lock files (frontend/pnpm-lock.yaml, backend/pnpm-lock.yaml)
- Added cache-dependency-path to setup-node for each workflow
- Simplified root package.json to only include prepare script for husky
