KAFKA-18066: Fix mismatched StreamThread ID in log messages

[UladzislauBlok]

This PR fixes an issue where the thread name shown in log messages did not match the actual execution context. Previously, log entries displayed the context of the newly created thread, while the logger reflected the current executing thread. This mismatch led to confusion and made log tracing more difficult.

Logs before fix:
18:20:42.861 [main] INFO o.a.k.s.p.internals.StreamThread - stream-thread [streams-linesplit-68754e82-1561-4482-a6cb-9f4b486c84ca-StreamThread-1] Creating restore consumer client

Logs after fix:

Changes:

• Use logger without context to not have context
• Updated log messages to explicitly describe the thread being created
• Fixed instances where the log context reflected the current thread instead of the newly created one
