Add configurable entity set name resolution

[PavilsG]

Summary

• Add an opt-in EntitySetNameResolver for parameterless For<T>() calls.
• Define and document the resolution order: custom resolver, [EntitySet] attribute, then built-in type-name convention.
• Preserve existing conventions when the resolver returns null, empty, or whitespace.
• Document a generic custom-attribute integration example.

Test coverage

• Resolver value overrides the built-in conventions.
• Resolver value overrides [EntitySet].
• Whitespace falls back to [EntitySet].
• null falls back to pluralization.
• The explicit For<T>(entitySetName) overload does not invoke the resolver.

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" (703 passed)

Pull Request Overview

This PR implements a configurable entity set name resolution mechanism. The implementation establishes the required resolution order: custom resolver, followed by attributes, and finally default naming conventions. Codacy analysis indicates the code is up to standards. No issues were found that should prevent merging.

Test suggestions

• Resolver value overrides the default pluralization convention
• Resolver value overrides the [EntitySet] attribute
• Resolver returning whitespace falls back to the [EntitySet] attribute
• Resolver returning null falls back to the pluralization convention
• Explicit entity set name in For call prevents resolver invocation
