Add disk space display to runner capabilities page

- Add DiskInfo struct to RunnerCapability for disk space data
- Add disk space progress bar with color coding (green/yellow/red)
- Add Int64ToFloat64 and DivideFloat64 template helper functions
- Add locale strings for disk space labels and warnings
- Show disk usage percentage, free space, and total space
- Display warning icons when disk usage is high (85%+) or critical (95%+)
