Make exec approval content scrollable when commands are too long to fit
on screen. Previously, long commands (like Python scripts) would push
the action buttons off-screen, making it impossible to approve/deny.
Changes:
- Wrap command/meta content in scrollable `.exec-approval-content` div
- Add max-height constraint to card (viewport - padding)
- Use flexbox layout to keep header and buttons always visible
- Content area scrolls independently in the middle
Fixes issue where users couldn't see approval buttons for long exec requests.
