test: update integration tests for Echo v5 compatibility

Update all integration test files to work with Echo v5 changes.

Changes in new_fixes_test.go:
- Update test helper signatures for *echo.Context
- Fix context handling in test assertions

Changes in security_test.go:
- Update security test signatures for Echo v5

Changes in test_helpers.go:
- Update test setup for Echo v5
- Fix context type usage in test helpers

Changes in websocket_test.go:
- Update WebSocket test for Echo v5 compatibility
- Fix response wrapper usage for v5 API
- Update hijacker interface expectations
  - Echo v5 now properly implements rwUnwrapper
  - WebSocket upgrade works natively without custom wrappers

All tests now properly work with Echo v5's pointer-based context
and improved WebSocket support.
