[BUGFIX] Fix date generation in AdminPanel preview

This patch fixes multiple issues when generating a date in AdminPanel's
preview module:

- The order of the date segements is changed to have a valid ISO format
- Months are 0-based in JavaScript (0 = January, 11 = December), for this
  reason, +1 is added to have a valid date string

Resolves: #87060
