feat(consents): auto-grant data:<provider> on connect; remove agent: consents (ADR-0015)

- integrations.ts: grant data:<provider> on OAuth callback, revoke on disconnect
- Backfill migration: INSERT OR IGNORE data:<provider> for all active tokens
- Agent manifests: drop agent:<id> from required_consents (momentum, time-of-day,
  overdue-task, recent-patterns, health-vitals) — per-agent control is a preference
- eligibility.ts: update comment to reflect data:-only consent model
- test_manifest.py: assert no agent: consents remain in any manifest
- migrations.test.ts: backfill idempotency tests for issue #127
- Dockerfile.api: drop --offline flag (fixes ERR_PNPM_NO_OFFLINE_META)
