Opt-in to_dict over __table__.columns: auto-isoformat datetimes,
*_encrypted always dropped, __serialize_exclude__ for redacted columns,
serialize_extra() for computed fields (named to dodge ServerMetrics'
literal 'extra' column). 20 purely-mechanical to_dicts across 15 files
convert; genuinely custom shapes keep their hand-written methods (plan
75 §F's ruling stands). Field selection stays api/_query.py's job.
Gate: key-for-key parity against the pre-conversion key sets frozen
from git HEAD (only the Timestamp pair may be additive).

Introduce programmatic API features and observability: add API Key management, API usage analytics, webhook event subscriptions, and OpenAPI docs. New models (ApiKey, ApiUsageLog, ApiUsageSummary, EventSubscription, EventDelivery), services (api_analytics, api_key, event, openapi), and blueprints (/api-keys, /api-analytics, /event-subscriptions, /docs) were added and registered in create_app. Middleware for API key authentication, buffered analytics logging (with a flush thread), and enhanced rate limiting (custom key function and response headers) were implemented; RBAC was updated to accept API key auth via an auth_required decorator. Background threads for hourly aggregation and event retry were added; security CSP updated to allow resources for Swagger UI. Frontend settings UI and styles were added/updated for API keys and webhooks, and requirements were updated.
