Debug stream should have search functionality

[vbar]

The other log views could use it as well (and other IDEs usually include it), but for debugging it's critical - even the simplest logs are too big to just see what I'm looking for...

I think this is an enhancement feature (we can make do with browser's built in search for now). We could explore if there's a way to use the monaco editor search or a similar package with debug stream searching, this would probably make debugging a bit easier for developers.

reasons:

• browser search cannot search inside collapsed rows
• browser search might not have regexp & case matching

Also, browser search won't be limited to the log - for example when searching for an account number, it will also find it in the list of accounts.
