Add cron job to docker image for graph calculations

[NotGovernor]

This is a real dead-in-the-water issue for me as I cannot shrink my site / vault. Any help would be greatly appreciated.

Describe the bug As I added more and more files to this vault over time the initial load times have climed such that recently I've started getting the following error on the console:

[11-Apr-2024 01:26:09] NOTICE: fpm is running, pid 1
[11-Apr-2024 01:26:09] NOTICE: ready to handle connections
172.19.0.3 -  11/Apr/2024:01:26:26 +0000 "GET /index.php" 500
NOTICE: PHP message: PHP Fatal error:  Maximum execution time of 30 seconds exceeded in /var/www/perlite/helper.php on line 478

To Reproduce I'm not entirely sure, but it seems to be related to the quantity of files in the vault. I'm currently around 600 md's and another 600 images.

Device (please complete the following information): Client device doesnt matter. It's a server issue. Running in docker. 2 vcpu's 4 gb ram.
