fix maru clients log names

[fluentcrafter]

Note

Standardizes Maru client logger names and refactors test Log4j setup to use builder + Configurator.

• Logging:
  • Logger names: Use maru.clients.l1.linea and maru.clients.l2.eth.el in app/src/main/kotlin/maru/app/MaruAppFactory.kt.
  • Test Log4j config (jvm-libs/test-utils/src/main/kotlin/maru/test/cluster/Configuration.kt):
    • Build console appender with pattern and SYSTEM_OUT target; attach layout directly.
    • Configure specific loggers with additivity=false and Console appender.
    • Initialize via Configurator.initialize(builder.build()) (replacing manual LoggerContext updates).
