test: kill act env warnings (globalThis flag + _notify act wrapper)

Browse Source 
- setupTests.js: set globalThis.IS_REACT_ACT_ENVIRONMENT = true (RTL reads
  getGlobalThis, not global). Kills 'environment not configured for act'.
- _mock-db.js _notify: set flag true around subscriber cb, restore prev
  after. RTL waitFor flips flag false mid-poll -> act() warned. Now clean.
- 146 act warnings -> 0.
