[canton-3.4] Enable force ACS pruning of 30 days for SVS

[moritzkiefer-da]

follow-up:

• Add cluster alert if oldest event is older than the participant pruning window #3109
• enable default 30 days pruning only for SVs (not validators)
• we have to wait for https://github.com/DACH-NY/canton/issues/29513

canton issue https://github.com/DACH-NY/canton/issues/28249

...and add integration test to confirm it works (see #3066 which you probably want to complete first).

[moritzkiefer-da]

integration test definitely makes sense but honestly I'd consider cluster alerts for the oldest event being older than the pruning window to be more important here.
