Add operationId to OpenAPI spec

[nathanjcochran]

This PR adds operationId fields to the OpenAPI specification and regenerates the API client types, resulting in clearer and more concise method names.

Changes

• Added operationId fields to all endpoints in openapi.yaml
• Regenerated API client types using go generate ./internal/tiger/api
• Updated all references to use the new method names (e.g., GetServicesWithResponse instead of GetProjectsProjectIdServicesWithResponse)

This is a small quality of life improvement that makes the code easier to read and maintain.
