Tweak GET /workflows/{workflow_id}/logs output

Current situation

By default, new GET /workflows/{wf_id}/logs endpoint returns logs with max_command_length=15, step_depth=0, job_depth=0.

Desired outcome

This endpoint should return non truncated and less verbose logs (almost same as opentf-ctl get workflow command defaults, max_command_length=0, step_depth=1, job_depth=1).
