Subject: [PATCH] Restructure AI settings into 3 cards and add AI Chat
 enable/disable toggle

Splits the AI tab into Configuration, Categorization, and Chat sections
with independent feature toggles. Both toggles are disabled when Ollama
URL or model is not configured. ChatPanel FAB is gated on isChatEnabled.
