chore(logging): runtime-reconfigurable trace configuration

[CommanderStorm]

This is like the previous PR a version of tracing

• feat: add martin-tracing-utils for configuring tracing (1/3) #1747

So by now we have had

• the one where I configured everything 3x => did not work due to too much duplication
• then was with the new crate and parsing/ intialising staticly
• and now runtime-reconfiguration

Honestly, I still like the extra crate more.
Much more readad and extendable in the future.

The runtime reconfiguration of formatting options is tricky as I need to get around some compiler limtations.
Changing the log level the same way is sadly not as simple, this is where I am hitting the 'static-requring brick wall.
There are also some heavy tricks to allow for runtime recajigling of the log format (see the boxing and the reload layer).

I suspect that there is at least a bit of performance impact of all this work. Likely not enoguh to make a difference anyhow.

Before I do this work, shoud we go back to #1747 as a more reasonable approach?

• Adds a new LogFormatOptions enum with support for multiple log formats (Full, Compact, Bare, Pretty, JSON)
• Implements ReloadableTracingConfiguration struct to enable runtime reconfiguration of logging format
• Integrates tracing configuration with the application's configuration system and CLI arguments
