Description

This PR enables lb4 discover to automatically detect database strict mode and inject jsonSchema.maxLength alongside the length property, preventing unhandled database truncation errors.

Purpose and Context

When the database is in strict mode and validation relies solely on model metadata length limits, requests exceeding column length fail with generic database errors.

@property({
  type: 'string',
  length: 100,
})
name: string;

Adding jsonSchema.maxLength ensures client-side validation catches data length violations before requests reach the database layer.
