RequestValidation extension

Adds request validation helpers to HttpRequest.

This extension provides convenient field-level and schema-level validation for incoming form data. It also preserves submitted input in session state and stores validation errors for later retrieval.

Example:

final ok = await request.validate(
  field: 'email',
  rules: [Rule.required, Rule.email],
);
on
