What was happening

Two cache-related bugs were causing confusion:

• Archived documents could still appear briefly when navigating to a document module, creating "phantom" entries
• When switching from one client to another, previously viewed documents from the old client could remain cached and appear momentarily

What we fixed

Switching clients now clears the document cache completely. The app follows the mental model you'd expect: selecting a new client gives you a clean slate. Archived documents are also properly filtered out of all document fetches, so they never appear where they shouldn't.
