test(backend): add boundary validation suite for CreateMarketDto (#1280)

[Francis6-git]

Description:
Added a dedicated unit test suite (create-market.dto.spec.ts) that invokes class-validator's validate() directly against DTO instances to test all field boundary constraints in isolation.

Changes Made:

1. New File: backend/src/markets/dto/create-market.dto.spec.ts

2. Coverage Highlights:

• Happy Path: Asserts 0 validation errors on fully valid payloads.
• Title: Verifies minLength, maxLength, isNotEmpty, and isString.
• Description: Verifies minLength, maxLength, and isString.
• Category: Verifies isEnum.
• Outcome Options: Verifies isArray, arrayMinSize (minimum 2), arrayMaxSize (maximum 10), and element string types.
• Date Validation: Verifies isFutureDate on end_time and isAfterEndTime on resolution_time.
• Stroops / Stake Bounds: Verifies isNumberString formatting for min/max stake stroop values.
• Creator Fee: Verifies min (0), max (500), and numeric type constraints.
• Extra Properties: Documents class-validator behavior regarding un-decorated extra properties.

Closes #1280
