Change LVM /root def to adapt dynamically (#4005)

h8d13 · web-flow · commit 1227babd8cf6 · 2025-12-22T22:05:30.000+11:00
* Change def size from 20 -&gt; 32
Rest is still calculated from available - root.

* Use the existing process_root_partition_size():
For LVM just like regular disk best-effort.
This is only for single disk layouts.
