fix: align Flutter API repositories with backend routes (Fase 3 prep)
- api_service_repository: use correct endpoints (/services/me, /services/professional,
/professional/requests, /professional/history, /professional/calendar)
instead of broken /services?userId= query params
- api_service_repository: fix status string↔enum, createService DTO,
paginated {data,meta} response, stub setProfessionalScored/setUserScored,
extract professionalId from nested professionals.user_id
- api_score_repository: fix /comments/user/:id and /comments/professional/:id
- api_professional_repository + api_user_repository: handle paginated response
