refactor(personas): improve type safety for persona configs

- Rename PersonaConfig → OrchestrationPersona in personas/types.ts
  to avoid confusion with agent/persona.ts:PersonaConfig
- Rename PERSONAS_CONFIGS → ORCHESTRATION_PERSONAS for clarity
- Remove duplicate inline configs in persona.ts, use shared constant
- getPersonaConfig now returns OrchestrationPersona type

Eliminates config duplication and clarifies type naming.
