Recording fails without write permissions on default recording directory

[emergenz]

8:48:11 PM [error] Autostart recording failed unexpectedly: Error: EACCES: permission denied, mkdir '/scratch/crowd-code/crowd-code-6d31bb9a-32c4-4dba-bf08-12bfb76a46201751222850245-2025_06_29-20.48.11.677'

Usually mostly an issue on e.g. HPC clusters.

Issue is that on HPC, multiple users might write onto the same file since /tmp/ is shared.

Fix is to append UUID to path.
