Option to save process snapshots during high cpu and memory utilization

Please add an option "Save ps snapshot" to the CPU and Memory checks which saves the actual ps section in the details.

Use Case
During periods of high server utilization, server owners and application managers often need to identify which processes consume the most CPU or memory. This information is especially useful for processes that are not regularly monitored but can unexpectedly cause issues, such as backup jobs, user processes or irregularly running tasks.

Currently, it is often not possible to retrospectively determine which specific processes were responsible for performance degradation at a given time, nor to identify whether the same processes are repeatedly causing problems.

Benefit
The relevant process data is already collected by Checkmk. By adding an option to save snapshots, this information would finally become accessible in a structured way. It simplifies troubleshooting and allows teams to identify recurring performance patterns directly within Checkmk, without the need to access other tools, correlate external data sources or rely on AI-based analysis tools.
