Approval dialog unscrollable when Bash command contains large payload

Description

When a Bash tool call contains a large inline payload (e.g. a JSON file written via heredoc for a Jira REST API call with ADF content), the approval dialog renders the entire command verbatim. There is no scroll capability on the dialog, so the Approve/Deny buttons are pushed off-screen and unreachable.

Steps to reproduce

1. Use Claude Code (Desktop app, Windows)
2. Trigger a Bash tool call that writes a large JSON file (e.g. ~200+ lines) via heredoc and then runs curl
3. The approval prompt appears with the full command text
4. The Approve/Deny buttons are below the visible area with no way to scroll down

Expected behaviour

The approval dialog should either:

• Be scrollable so the user can reach the Approve/Deny buttons
• Truncate/collapse the command preview with an expand option
• Float the Approve/Deny buttons at the bottom of the dialog regardless of content length

Screenshot

User-provided screenshot shows the dialog filled entirely with raw JSON, buttons not visible or reachable.

Environment

• Claude Code Desktop app (Windows 11)
• Large Bash command with heredoc JSON payload (~4KB ADF content)
