Add event-driven tasks via Gitea webhooks

Webhook endpoint at /api/webhooks/gitea receives Gitea status events,
matches them against configurable event triggers with conditions
(event type, repo glob, state, context), renders task templates with
{{variable}} substitution, and creates harness tasks automatically.

Includes circuit breaker: after N consecutive task failures from the
same trigger (default 3), the trigger auto-disables. Re-enable
manually via PATCH /api/event-triggers/:id.

New tables: harness_event_triggers (rules + circuit breaker state),
harness_event_log (audit trail + dedup via X-Gitea-Delivery).
