viettranx 0c44149fad test: speed up retry/cron/facebook tests, drop coverage ratchet gate
Slow tests were dominating CI feedback time and AI dev loop because they
waited through real exponential backoffs and 1s ticker intervals.
Test-only override pattern keeps production behavior 100% identical.

Speed wins (no-race wall-clock per package):
- internal/vault            16.3s -> 0.6s   (-15.7s)
- internal/cron             11.7s -> 1.5s   (-10.2s)
- internal/channels/facebook 6.3s -> 3.0s   (-3.3s)
- Full -race ./... suite     90s+ -> 51s

Changes:
- vault: new fastBackoffsForTest(t) helper overrides enrichRetryBackoffs
  + enrichRetryTimeouts to 1ms in 3 retry tests; drop 2 duplicate tests
  (FirstAttemptSuccess, MaxRetriesConstant)
- cron: extract runLoopTickInterval as package var (default 1s); test-only
  setFastTick(t) helper shortens to 20ms so 6 scheduler tests no longer
  sleep 1.5s each waiting for a tick
- facebook: extract graphBackoffBase as package var (default 1s); newFakeGraph
  helper shortens to 1ms so HTTP retry tests don't burn 6s of real waits

Coverage ratchet removed:
- Delete scripts/check_coverage.go + scripts/coverage_thresholds.json
- Remove "Coverage ratchet gate" CI step
- Keep coverage profile + go tool cover summary as informational only
- Philosophy: signal over coverage %. Forced tests to bump % were the
  root cause of the slowness this commit unwinds.

Production behavior unchanged. Coverage profile shows isolated package
coverage matches prior thresholds (vault 27.4%, cron 73.7%, facebook 81.9%).

//
// Production behavior is 100% unchanged — only the test sees the fast values.
// Original values are restored via t.Cleanup so parallel/sequential tests
// remain isolated.
//
// Use in any test that exercises callClassifyWithRetry / chatWithRetry with
// >1 attempt. Do NOT use in tests that explicitly assert on the default
// values (e.g. TestCallClassifyWithRetry_RetriesAndBackoffs).
