refactor(schemas): rename Agent* schemas and WS frame types to Scout*

Rename all Pydantic models referring to the scout subsystem:
AgentConfig → ScoutConfig, ContentTypeConfig → ScoutContentTypeConfig,
AgentCatalogItem → ScoutCatalogItem, AgentCreationCheckRequest/Response →
ScoutCreationCheckRequest/Response, AgentTriggerRequest → ScoutTriggerRequest,
AgentRunLogResponse → ScoutRunLogResponse.

LLM-helper agent schemas in app/agents/* are untouched.
