feat(dbal): generate Prisma schema for email models

- Updated gen_prisma_schema.js to parse YAML entity schemas
- Generated Prisma models for EmailClient, EmailFolder, EmailMessage, EmailAttachment
- All email models include proper indexes and constraints from YAML definitions
- Schema generation now supports dynamic YAML parsing with fallback to core models
