feat(settings): add preferredOrg field to folder configuration

[bastiandoetsch]

Description

This PR adds support for configuring a preferred organization at the project level through the FolderConfig settings, and deprecates the global organization field in favor of this new project-level setting.

Changes:

• Added preferredOrg field to FolderConfig data class with default empty string value
• Added UI input field for preferred organization in SnykSettingsDialog, positioned below "Additional Parameters" in Project settings
• Implemented getPreferredOrg() method in FolderConfigSettings to retrieve the project's preferred organization
• Updated SnykProjectSettingsConfigurable to properly save and load preferredOrg settings
• Deprecated global organization field - Disabled the global organization text field in General settings and updated tooltip to guide users to use the project-level setting instead
• Added comprehensive test coverage with 10 new tests for preferredOrg functionality
• Fixed compilation errors in existing tests due to updated FolderConfig constructor

Jira: IDE-1366

The preferredOrg field allows users to configure a preferred organization at the project level, with the same behavior as Additional Parameters. The global organization setting in General settings is now deprecated in favor of this project-level configuration.

Failing test is due to missing CLI with protocol version 21. This is ok and can be ignored.
