chore: disable hdb v2 compression feature (#1405)

johannes-vogel · web-flow · commit 5c351fc5a5ce · 2025-11-06T20:09:05.000+01:00
compression is cpu intense and therefore disabled by default.

also our internal tests should issues with failed packet decrompession.
I will try to create an issue on hdb side for that.
