Do not convert/calculate on custom variable content

[log1-c]

Describe the bug

We user the custom variable/field notification_delay on service checks to delay notifications for specific kinds of checks.
When entering big numbers like 2592000 they get converted when shown in the webinterface

Expected behavior

Show the content of the variable as is

Seems to be related to the PHP version. I cannot reproduce this on 8.x, only on 7.x.

Given you're right, whatever PHP is doing here is scary:

MariaDB [icingadb]> select flatvalue from customvar_flat where flatname='dummy_statee'\G
*************************** 1. row ***************************
flatvalue: 2e+18
1 row in set (0.001 sec)

MariaDB [icingadb]>

Yep, in Go fmt.Sprintf("%v", 2000000000000000000) == "2e+18". Our Flatten() uses this.
