Volume Label Truncation Issue
The label value truncation introduced in v2.20.1 could produce values
starting with a non-alphanumeric character (e.g. -), which is invalid
per the https://docs.hetzner.cloud/reference/cloud#description/labels.
Truncated values are now stripped of leading non-alphanumeric characters
to ensure they remain valid.
