Use formulas so extensions follow skirting height automatically

Drive an extension's value with a formula referencing the skirting height so it updates on its own when that height changes.

1. When an extension or similar component should track another dimension such as skirting height, drive its value with a formula referencing that dimension instead of entering a fixed number.

2. Then when the skirting height changes, the extension updates automatically and there is no need to re-enter values manually.
