Adds camelCase support for encrypted field mappings

Extends encrypted field mappings to include camelCase variants
to support consistency and compatibility with different naming
conventions. Updates reverse mappings for Drizzle ORM to allow
conversion between camelCase and snake_case field names.

Improves integration with systems using mixed naming styles.
