[Bug]: New logs API breaks backward compatibility withdstack logs #2909
Description
Steps to reproduce
- Use server from master and cli 0.19.18
- Start a run and try to read its logs with
dstack logs. You'll get an error because the old CLI tries to decode base64-encoded logs but the server returns logs in plaintext (after [Feature] Strip ANSI codes from run logs and store them as plain text instead of bytes #2876)
