docs(phase-07.1): add Nyquist VALIDATION.md — nyquist_compliant: true

All 6 tasks covered: 3 backend integration tests (pytest, green) + 3 frontend
unit tests (vitest, green). 0 manual-only. Gap audit resolved 3/3 missing gaps.

+All 11 test functions exist and are implemented. 10 pass in unit mode; 1 (`test_load_provider_config`) is correctly gated behind `INTEGRATION=1` because it requires a live PostgreSQL session. The test implementation is complete and correct — it is not a gap.
