What/Where is the issue ?

String variables that starts with number and are too long are being reflected in Scientific notation in Optimize.

Environment: C7/ C8SaaS/ C8SM

Optimize version : 3.10.4, 3.10.6, 3.11.3
ES version : 7.17 / 8.8
OS + Browser version : Chrome

Steps to reproduce:

1. Start a process instance with Variable string.
2. Ensure that the string variable have some values in the following format and is too long > 50 characters:
   <number><string>. e.g. 123123 adasdasda dasdas dasd asdasdasdasdasdasdasdsa...
3. Create a report for process definition.
   Report Setup Data Table
   View > Process Instance
   Measure > Count
   Group by > Variable: <aVariable>
   Visualization > Table
   3. Save Report

Observed behavior:

Expected behavior:

Actual String value should be reflected in Reports.

Additional Information:

Seems to be caused by OPT-5641 where we convert long number to exponential format.
We are checking for numbers with `isNaN` which does return `false` if the first couple of letters in string are numbers. This causes the string to be converted to exponential format.
