feat: log level validation + feedback for log events

[lcottercertinia]

Is your feature request related to a problem?

Not clear what features / info is available at which log levels. If a certain level is needed we should let the user know.

e.g

• On the DB tab level needs to be finest to have query plan info.
• To show heap usage Apex needs to be finest
• Need to compile a full list + decide how to show this.

Share optimal defaults Optimal settings and available events at each level

I would like to know what log levels are best to get the most out of the analysis

1. The simplest is to tell the user that finer will consume more time than fine and give them some good defaults to use.
2. Maybe the over head of each logging level can be calculated and timings could be adjusted to be relative? or show that overhead visibly? So that smaller methods are not affected as much.
