fix(event-handler): preserve metadata constraints in parameter validation

[leandrodamascena]

Issue number: closes #7600

Fixes a regression introduced in PR #7227 where annotated_types constraints (like Interval) were not being validated in request parameters.

The issue occurred in the copy_field_info() function when switching from FieldInfo.from_annotation() to copy(). While this preserved discriminator functionality, it discarded constraint metadata from nested Annotated types.

Changes

• Modified copy_field_info() to recursively extract and preserve constraint metadata while filtering out FieldInfo instances
• Updated get_field_info_annotated_type() to maintain consistency
• Added tests covering valid values, boundary conditions, and validation failures for both Body and Query parameters
