Fix 4 HIGH overflow bugs: scrollable Docker tiles, tables, tabs, app rows

- Dashboard: overflow-x auto on card td cells for Docker container grid
- Dashboard: text-overflow ellipsis on span.outer for long container names
- Main: overflow-x auto on tabpanels (ZFS Master, Boot Device, etc.)
- Docker/VM: overflow-x auto on .TableContainer wrapper
- Apps: overflow-x auto on .ca_homeTemplates card rows
- Apps: box-sizing border-box on .ca_appPopup to prevent card overflow
- Consistent glass scrollbar styling (thin, translucent) on all
