feat: add Automations and Events endpoint support

[christina-de-martinez]

Summary by cubic

Add full Automations and Events API support to the SDK so users can define, manage, and trigger workflows. Includes new models, client methods, and tests for end-to-end coverage.

• New Features

  • Automations: create/update/retrieve/list (filter by status), stop, delete; list runs (filter by status) and retrieve a run. Models added for automations, graph steps/edges, and runs.
  • Events: create/retrieve (by id or name)/list/update/delete (by id or name), and send events with contact_id or email plus payload. Models added for events and send responses.
  • Client surface: new async methods on IResend with implementations in ResendClient (ResendClient.Automations.cs, ResendClient.Events.cs) for all endpoints. Tests and local mock controllers cover these flows.

• Bug Fixes

  • Use key (not ref) for automation step identifiers in create/update payloads to match the API.
  • Mock: EventRetrieve response now reflects the route id/name to match the requested lookup.

^{Written for commit 7b48715. Summary will update on new commits.}

Confidence score: 3/5

• There is a concrete functional risk in tools/Resend.ApiServer/Controllers/EventController.cs: EventRetrieve ignores the route id and always returns a hard-coded event, so clients can receive incorrect data.
• Given this is a user-facing API behavior bug with moderate severity/confidence, merge risk is moderate rather than high, but it should be corrected before relying on this endpoint.
• Pay close attention to tools/Resend.ApiServer/Controllers/EventController.cs - ensure EventRetrieve uses the requested id to fetch and return the correct event.
