feat: weni run active agents cli backend

[MatheusLeall]

• feat: extend weni run to support active agents (PreProcessor + Rules)
  • new RunRequestModel with type discriminator (active | passive)
  • introduce Strategy pattern in app/services/runs/ with tool_strategy (passive) and active_strategy (active)
  • active runs reuse ActiveAgentProcessor to build the Lambda zip and stream results in the same NDJSON contract as the passive flow
  • active test_event now mirrors the active Lambda template (payload, params, credentials, project, project_rules, ignored_official_rules, global_rule); JWT is injected into project.auth_token
