Pull request overview

This pull request adds comprehensive unit tests for various utilities and components in the CloudBeaver codebase, unskips previously disabled tests, and enforces named functions through ESLint configuration.

• Adds unit tests for core utilities (isIp, isBrokenImage) and hooks (useSearch, useFuzzySearch, useObjectRef, useErrorDetails, useAdministrationSettings, useCombinedHandler)
• Adds unit tests for UI components (UploadArea, StaticImage, IconOrImage)
• Updates ESLint configuration to enforce named functions with the func-names rule
• Unskips and fixes previously disabled tests in getTextFileReadingProcess, app-init, and useCombinedHandler
• Creates test utility mocks (sMock, useSMock, useObservableRefMock) for consistent testing patterns
