fix: standardize card/list action buttons and hover states (refs #51)

- Documents page: Convert from text buttons to icon buttons (Eye for
  View Details, Trash for Delete), add card hover shadow effect,
  convert to MUI components for consistency
- Fuel Logs: Add row hover background effect on list items
- Maintenance Records: Add card hover shadow effect
- Maintenance Schedules: Add card hover shadow effect

All changes follow the VehicleCard pattern with:
- Light gray shadow/elevation on hover with 0.2s transition
- Consistent icon button styling with mobile-responsive touch targets
- Proper MUI component usage throughout
