As an IT Infrastructure Manager,
I want to schedule PRTG service or system restarts using relative date patterns (e.g., "every 2nd Thursday of the month"),
so that I can ensure restarts always occur on a predictable weekday and never unexpectedly fall on a weekend, reducing the risk of unattended restarts and aligning maintenance with my team's working hours.

Background:
One restart each month is recommended. But currently, only a day of a month is selectable. Which means the restart will happen during the week or on the weekend. It makes sense to have the option for e.g. every 2nd Thursday of a month so we know that it happens always during the week and not on a weekend.
Similar to the task scheduler in Windows.

The ability to add scheduling for reoccurring maintenance schedules is critical. Use cases for our business is the following
1. Monthly Patch Updates (all nodes monthly one date a month)
2. WAN circuit maintenance - notified by circuit provider in advance prior to maintenance and window is in the middle of the night - until this is implemented will have to keep in a separate ledger and mute day of.

We also need this feature as our server is set to restart on a specific day each month and after each reboot some error notifications are triggered.
the current weekly schedule options cant be used to prevent this.
