refactor: remove mock data and finalize n8n data schema

- Removed all hardcoded MOCK_ATTENDANCES, USERS, and TENANTS generators from constants.ts since the system is now production-ready.

- Renamed 'summary' to 'title' in the database and across all frontend components for clarity.

- Added 'full_summary' to the attendances schema to explicitly store the large, detailed AI analysis texts from n8n.

- Updated the 'Resumo da Interação' UI to render the 'full_summary' without adding any artificial filler text.

- Localized all dates and times across the dashboard to Brazilian formatting (pt-BR).
