Fix GlobalSettings crash when JFrog CLI is not installed (XRAY-145646)

[Jordanh1996]

Summary

Fixes XRAY-145646 — IntelliJ plugin 2.9.0 fails to start on Windows with:

PluginException: Cannot init component state (GlobalSettings)
Caused by: NullPointerException: Cannot invoke Log.error() because "this.log" is null
  at JfrogCliDriver.runVersion → isJfrogCliInstalled

Root cause: ide-plugins-common 2.4.x (#525) changed JfrogCliDriver(Map, String path) to JfrogCliDriver(Map, Log). ServerConfigImpl.readConnectionDetailsFromJfrogCli() still passed null as the second argument — previously the CLI path, now the Log. When jf is not on PATH (common on Windows), isJfrogCliInstalled() calls log.error() and NPEs during GlobalSettings init.

Fix: Pass new NullLog() instead of null when constructing JfrogCliDriver.

Test plan

• Reproduced NPE on Windows VM without jf on PATH (broken 2.9.0 build)
• Verified fixed build: IntelliJ starts, Global Configuration saves and persists across restart
• ConnectionDetailsFromCliTest updated and passes
