test: add unit tests for relay_validator and relay_selector

- test_relay_validator: Schnorr verify + SHA-256 event ID, tamper detection
  (ID, sig, content), invalid JSON, missing fields, result_string
- test_relay_selector: relay scoring (NIP-77 bonus, latency tiebreak,
  failure penalty, dead relay handling)
- Updated Makefile with new test targets
- Added configTICK_RATE_HZ to FreeRTOS stubs
