Implement v1.0.3 quick wins: Date ranges, EntityReference.Name, and null handling
This commit implements the top 3 priority quick wins identified from upstream repository analysis, resolving multiple long-standing issues reported by users. **Quick Win jordimontana82#1: Fix Date Range Operators** (Resolves jordimontana82#588, jordimontana82#587, jordimontana82#551, jordimontana82#543) - Modified XrmFakedContext.Queries.cs to include full end day (23:59:59.999) - Fixed: ThisMonth, LastMonth, NextMonth, ThisYear, LastYear, NextYear - Fixed: ThisWeek, LastWeek, NextWeek, InFiscalYear - Fixed: Between operator for date ranges - Added DateRangeOperatorTests.cs with 9 comprehensive tests **Quick Win jordimontana82#2: EntityReference.Name Population** (Resolves jordimontana82#555) - Modified RetrieveRequestExecutor.cs to populate EntityReference.Name - Modified RetrieveMultipleRequestExecutor.cs to populate EntityReference.Name - Automatically populates Name from referenced entity's primary name attribute - Added EntityReferenceNameTests.cs with 9 comprehensive tests **Quick Win jordimontana82#3: Null Reference Exception Fixes** (Resolves jordimontana82#608, jordimontana82#607) - Added defensive null checks in TranslateConditionExpressionLike - Added defensive null checks in TranslateConditionExpressionContains - Added defensive null checks in TranslateConditionExpressionEndsWith - Added defensive null checks in TranslateConditionExpressionIn - Prevents crashes when null values present in query conditions - Added NullReferenceHandlingTests.cs with 15 comprehensive tests **Test Coverage:** - 33 new tests total across 3 test files - All tests verify both functionality and edge cases - Tests cover QueryExpression and FetchXML scenarios **Impact:** - Resolves 8+ upstream issues reported by community - Improves compatibility with real Dataverse behavior - Prevents common crashes in query engine - Enhances developer experience with auto-populated EntityReference names All changes are backward compatible and follow existing code patterns.
