Update test baselines for LEAST/GREATEST functions to match EF Core 10 SQL generation

- Updated Where_math_min and Where_math_max: Now correctly expect LEAST/GREATEST in SELECT clause
- Updated nested tests: EF Core 10 optimizes nested calls by flattening them into single LEAST/GREATEST calls
- All 12 Math.Min/Max tests now passing with correct SQL expectations

Examples:
- Math.Min(a, Math.Min(b, c)) generates: LEAST(a, b, c) instead of LEAST(a, LEAST(b, c))
- .Select with Math.Min generates: SELECT col, LEAST(...) AS Result instead of just selecting columns
