Summary

• Replace the static "Paid Plan Required" card above the composer with a popup that opens when a free-plan user sends a message
• Send stays enabled; the draft is kept when the popup opens
• The popup also opens for sends that skip the composer: "Send now" on a queued message and handoffs from other surfaces (e.g. Troubleshoot in Chat), which previously dropped silently once the card was gone
• One ChatPlanModal per shell (workspace chrome and the extension), opened through a small stores/modals/chat-plan store
• Extract the upgrade link, permission check, and "ask an admin" copy into usePlanUpgradeLink, shared by the popup and the in-chat usage card, so both resolve the same destination
• Popup contents mount only while open, so a closed popup reads no session or billing context
