feat: regenerate API client from OpenAPI spec

[convoy-sdk-bot]

Automated regeneration via OpenAPI Generator (php) from docs/v3/openapi3.yaml on frain-dev/convoy main. Hand-written SDK code (src/ outside src/Client/, incl. webhook verify) is untouched by the sync script.

Note

Medium Risk
Public generated method signatures change: Events API methods insert a new $body argument, which can break positional callers. Delivery methods only add a trailing optional $query, which is safer.

Overview
Regenerates generated Convoy PHP client APIs from the latest OpenAPI spec so list/replay/retry calls can send the new search filters.

Events (EventsApi): getEventsPaged, batchReplayEvents, and countAffectedEvents take an optional body query param (URL-encoded JSON payload match, ANDed with query). query docs now describe id/idempotency/type/source matching plus JSON containment. This inserts $body as the second positional argument, so positional callers of those methods will shift remaining args.

Deliveries (EventDeliveriesApi): getEventDeliveriesPaged and batchRetryEventDelivery gain optional query (delivery id, event id, event type prefix, endpoint name).

List endpoints also map 504 (and events list 403) to the existing error model. DatastoreProjectConfig.search_policy docs describe the optional lookback duration for payload search.
