fix(core): initialize lastTokenRefresh for stamped tokens to prevent unnecessary refreshes

[ryanbonial]

Description

Added a createLoggedInAuthState helper function to properly initialize the lastTokenRefresh timestamp for stamped tokens. This prevents unnecessary token refreshes when the tab becomes visible after being hidden, as the system now tracks when tokens were last refreshed.

The implementation:

• Automatically sets lastTokenRefresh for stamped tokens (containing -st)
• Preserves existing timestamps when updating tokens
• Doesn't set timestamps for non-stamped tokens
• Moved auth state types to a dedicated file for better organization

What to review

• The implementation of createLoggedInAuthState in utils.ts
• Usage of the helper throughout the codebase where auth states are created
• The comprehensive test cases that verify the behavior with different token types
• The fix for visibility change handling that now respects the timestamp

Testing

Added extensive test coverage for the new functionality:

• Tests for createLoggedInAuthState with various token types and parameters
• Tests for visibility change behavior with recent and old timestamps
• Tests that verify the fix prevents unnecessary refreshes
