Add proxy_failure_limit param to make_tiered_cycler (default 3).
Individual proxies hitting the limit are marked dead and permanently
skipped. next_proxy() auto-escalates when all proxies in the active
tier are dead. Both mechanisms coexist: per-proxy dead tracking removes
broken individuals; tier-level threshold catches systemic failure.
- proxy.py: dead_proxies set + proxy_failure_counts dict in state;
next_proxy skips dead proxies with bounded loop; record_failure/
record_success accept optional proxy_url; dead_proxy_count() added
- playtomic_tenants.py: pass proxy_url to record_success/record_failure
- playtomic_availability.py: _worker returns (proxy_url, result);
serial loops in extract + extract_recheck capture proxy_url
- test_supervisor.py: 11 new tests in TestTieredCyclerDeadProxyTracking

utcnow_iso() now produces 'YYYY-MM-DD HH:MM:SS' (space separator) matching
SQLite's datetime('now') so lexicographic comparisons like
'published_at <= datetime(now)' work correctly.
Also add `id DESC` tiebreaker to get_ledger() ORDER BY to preserve
insertion order when multiple credits are added within the same second.

- test_supervisor.py: 28 tests covering load_workflows, resolve_schedule,
is_due, topological_waves, and proxy round-robin / sticky selection
- test_feature_flags.py: 31 tests covering migration 0019, is_flag_enabled,
feature_gate decorator, admin toggle routes, and full toggle e2e flows
- conftest.py: seed feature flags with production defaults (markets=1,
others=0) so all routes behave consistently in tests
- Fix is_flag_enabled bug: replace non-existent db.execute_fetchone()
with fetch_one() helper
- Update 4 test_waitlist / test_businessplan tests that relied on
WAITLIST_MODE patches — now enable the relevant DB flag instead
