- Add FluentValidation validators for CreateFilamentRequest and UpdateFilamentRequest with comprehensive validation rules (required fields, string lengths, hex color format, weight constraints including WeightRemainingGrams <= WeightTotalGrams, purchase price range) - Add FluentValidationFilter action filter that auto-runs FluentValidation validators for all API controller actions before execution, returning 400 with structured error details - Register FluentValidationFilter in DI and add it to MVC controller filters in Program.cs - PUT endpoint was already implemented in FilamentsController with proper validation, 404 handling, FK existence checks, serial uniqueness check, and weight constraint check - This change ensures FluentValidation rules are enforced consistently via the pipeline
