Move "reservation name" field to the last column in static leases list

[cotosso]

In the Static Leases list, the "Reservation Name" field is often empty, creating gaps in the displayed table.

To improve readability and alignment, it is proposed to move this field to the last column. This also aligns with its position in the drawer.

Steps to Reproduce

• Navigate to the Static Leases list.
• Observe that the "Reservation Name" column appears before other populated columns, creating visual inconsistencies when empty.

Proposed Solution

• Move the "Reservation Name" column to the last position in the table.
• Ensure consistency with the drawer layout, where it is already positioned last.
