feat: `useMemoWithPrevious` React hook

[yomybaby]

Resolves #2819

Changes: Introduces a new useMemoWithPrevious hook to manage previous and current values with reset capability, replacing the manual useRef implementation in ContainerLogModal. This hook provides a more robust way to track state changes while maintaining previous values.

Implementation Details:

• Created new useMemoWithPrevious hook that returns both current and previous values along with a reset function
• Updated ContainerLogModal to use the new hook for tracking log line numbers
• Replaced manual previousLastLineNumber ref management with the new hook's resetPrevious functionality
• Improved state management when switching kernel IDs or changing log sizes

Testing Requirements:

• Verify log highlighting works correctly when switching between different kernels
• Confirm previous line numbers are properly reset when changing log sizes
• Check that log display maintains proper highlighting of new content
