Subject: feat(editor): Implement drawing tools and advanced undo/redo

This commit significantly enhances the web spectrogram editor by implementing core drawing tools (line, ellipse, noise) and a robust undo/redo system.

-  and : Added redo button and styling.

- : Implemented canvas event handling, dynamic shape previews, and the  logic for lines and noise rectangles.

- : Now reconstructs the spectrogram from a clean base, allowing proper undo/redo.

- : Uses an improved color gradient for better visualization.

- : Stores original spectrogram data for persistent state management.
