Hide Mintlify floating assistant input

Add CSS to hide Mintlify's full-width floating input pill (.chat-assistant-floating-input) at the bottom of pages. A documented comment explains the rationale: the pill dominates the bottom of articles on wide screens, so it's removed while keeping the navbar entry (#assistant-entry / #assistant-entry-mobile) and the expanded chat panel (#chat-assistant-sheet) intact. The rule uses display: none !important to reliably override the injected styles.
