feat(workflows): implement RunActivityWorkflow — T18

Browse Source 
workflows.py — RunActivityWorkflow:
  1. load_activity_definition(activity_id)
  2. resolve_context(context_sources)
  3. evaluate_templates (pure, called in-workflow)
  4. log_run({run_id, ...}) — run_id = uuid5(NAMESPACE_URL, activity_id:trigger_key)
  5. start_child_workflow(TaskExecutorWorkflow, ...) per task spec
     ABANDON parent-close policy (fire-and-forget)
  Returns {"run_id": str, "tasks_spawned": int}

activities.py — log_run updated:
  - now accepts run_id in run_payload (deterministic, passed from workflow)
  - uses pg INSERT ... ON CONFLICT (run_id) DO NOTHING for idempotency
