Fixes Volobox task VolosoftWorkspace#1860.

Summary

• Add [DynamicStringLength] on CreateLanguageDto / UpdateLanguageDto DisplayName (and MVC create/edit modal views) using LanguageConsts.MaxDisplayNameLength so overlong names return validation errors instead of SQL Server truncation 500s.
• Cover create and update with application tests that expect AbpValidationException when the display name exceeds 32 characters.

Test plan

• Build Application.Contracts and Web (net10.0)
• dotnet test filter DisplayName_Exceeds_MaxLength — both create and update tests pass
• Manually POST/PUT Language Management with display name length 33 → expect 400 on DisplayName; length 32 → succeed on SQL Server
