fix: Wire up interactive permission, question, and plan cards in PromptBar

- Broadcast PermissionRequest hook as claude-permission WS event
- Fix dedup bug where undefined requestId blocked all permission cards
- Add sendInput() to AgentTerminal for char-by-char PTY responses
- Make AskUserQuestion options clickable (sends option number to PTY)
- Add Approve/Reject buttons for ExitPlanMode plan cards
- Permission Allow/Deny now sends y/n to PTY instead of broken HTTP call
