v5 PR for the getNativeAccountId bug fix (#7960)

• Fall back to getting the native account id of the active account if no loginhint or sid is provided.

[Copilot]

Pull Request Overview

This PR fixes a bug in the native account retrieval logic by adding validation for empty or invalid account filters. When no login hint or SID is provided, the code now properly falls back to using the active account's native account ID instead of attempting to filter with invalid criteria.

Key changes:

• Added validation in CacheManager.getAccountInfoFilteredBy to detect and handle empty/invalid account filters
• Removed redundant filter validation from AccountManager.getAccount since it's now handled at the cache layer
• Added test coverage for the new validation logic

This looks like it changes the behavior of the API, is this intended?
