fix(onboarding,integrations,cycle): deep-link source chips + cycle settings wrench

- Onboarding 'more sources' chips anchor to their provider card
  (/settings/integrations#oura etc.); connection cards gain scroll anchors.
  Apple Health (no web card) stays on the page root.
- Cycle module gains a header settings wrench for parity with labs /
  medications / illness; the tab strip is now controlled so the wrench jumps
  to the settings tab and ?tab= deep-links keep working.
