chore: improve integration test infrastructure (#2126)
## Summary

Currently it's hard to debug integration tests because of all the extra logging/warnings/open handler issues (wasn't sure if I introduced an open handler or was existing). This fixes that.

- Bump Jest from v28 to v30 in api and common-utils packages, syncing with app's existing setup
- Replace legacy `preset: 'ts-jest'` with modern `createJsWithTsPreset()` spread pattern across all packages
- Fix open handles that required `--forceExit` and `--detectOpenHandles` workarounds
- Suppress noisy console and logger output during test runs via targeted mocks

## Changes

### Jest/ts-jest upgrade
- Bump `jest` 28 → 30, `@types/jest` 28 → 29 in api and common-utils
- Adopt `createJsWithTsPreset()` config pattern (matching app)
- Add `isolatedModules: true` to common-utils tsconfig to fix ts-jest warning with Node16 module kind
- Update snapshot files and inline snapshots for Jest 30 format changes
- Replace removed `toThrowError()` with `toThrow()`
- Fix team.test.ts inline snapshot that depended on dynamic Mongo ObjectIds

### Open handle fixes
- Add `close()` method to `BaseClickhouseClient` in common-utils
- Call `mongoose.disconnect()` in `closeDB()` (api fixtures)
- Add `closeTestFixtureClickHouseClient()` and call it in `MockServer.stop()`
- Fix common-utils integration tests to close both `hdxClient` and raw `client` in `afterAll`
- Disable `usageStats()` interval in CI to prevent leaked timers
- Remove `--forceExit` from common-utils CI/dev scripts and api dev script
- Remove `--detectOpenHandles` from all dev scripts

### Log noise suppression
- Use `jest.spyOn` for console methods instead of global console object override
- Add per-file `console.warn`/`console.error` suppression in test files that exercise error paths
- Mock pino logger module in api jest.setup.ts to suppress expected operational logs (validation errors, MCP tool errors, etc.)
- Use pino logger instead of `console.error` in Express error handler (`middleware/error.ts`)
- Add console suppression to app setupTests.tsx

## Testing
- `make ci-lint` — passes
- `make ci-unit` — 2177 tests pass, zero console noise
- `make ci-int` — 642 tests pass (606 api + 36 common-utils), zero log noise
