feat+fix(engine): Implement resource identifiers module + fix Temporal clashing workflow ID

[daryllimyt]

Features

• Implement (revamped utils) identifiers module, which contains a suite of methods, types, and validators for Tracecat resource identifiers.
  • We leverage pydantic's StringConstraint with regex + typing.Annotated to achieve runtime pattern checking
  • Also contains method to create action keys/refs and workflow run ids etc.
• Add ResourcePrefix to centralize all resource class identifiers

Changes

• Align our world view with Temporal - we distinguish between workflow, workflow execution (a running workflow instance), and workflow runs (a try/attempt of a running instance).
  • See updated contexts.RunContext

Testing

• Updated tests to use a fixed test id, workflow tests passing

Would prefer if gen_id was generate_id
