fix: resolve all TypeScript and lint errors in integration tests

- Fixed InMemoryTransport destructuring (object → array)
- Updated all callTool calls to new object syntax
- Changed getServerInfo() to getServerVersion()
- Added type assertions for response objects
- Fixed import paths and missing imports
- Corrected template and performance test type issues
- All 56 TypeScript errors resolved

Both 'npm run lint' and 'npm run typecheck' now pass successfully
