Add configurable entity set name resolution

[PavilsG]

Summary

• Add an opt-in EntitySetNameResolver to resolve entity-set names for parameterless For<T>() calls.
• Preserve existing [EntitySet] and pluralization conventions when the resolver returns null, empty, or whitespace.
• Document the option and add focused coverage for resolver override and fallback behavior.

Validation

• dotnet build PanoramicData.OData.Client.Test/PanoramicData.OData.Client.Test.csproj --no-restore
• dotnet vstest PanoramicData.OData.Client.Test/bin/Debug/net10.0/PanoramicData.OData.Client.Test.dll --TestCaseFilter:"FullyQualifiedName~UnitTests" (700 passed)

Pull Request Overview

The PR successfully implements the EntitySetNameResolver in ODataClientOptions, allowing for custom type-to-entity-set mapping. The implementation correctly prioritizes the custom resolver over existing attribute and pluralization conventions. Documentation in the README has been updated to reflect these changes.

While the core functionality and documentation are complete, there is a gap in the unit test coverage. Specifically, the scenario where the resolver returns null to trigger a fallback to default pluralization logic is not explicitly tested. All other acceptance criteria appear to be met.

About this PR

• The test suite does not currently include a scenario to verify that the system falls back to default pluralization logic when the custom resolver returns null. It is recommended to add this unit test to ensure full compliance with the fallback requirements.

Test suggestions

• Custom resolver provides a name, overriding all conventions
• Custom resolver returns whitespace, falling back to [EntitySet] attribute
• Custom resolver returns null, falling back to default pluralization logic

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Custom resolver returns null, falling back to default pluralization logic
