feat: add hide or show for media elements, mute or unmute for audio elements (#500)

* feat: create external tools section (#493)

* feat: create external tools section

* fix: better wording

* Feature, added hide or show for media elements, mute or unmute for audio elements both effective on timeline and preview panel, with overlay icon for indicating so and state storing,

* Minor UI vertical separator between magnifier and other buttons

* fixed the AbortError issue in the AudioWaveform component. The error was occurring because of a race condition during cleanup when the component unmounts.

* feat: implement bookmarking functionality in the timeline and project storage

- Added bookmark management methods in the project store for toggling and checking bookmarks.
- Updated the timeline component to display bookmark markers and integrate bookmark actions in the context menu.
- Enhanced the storage service to handle bookmarks in project serialization and deserialization.
- Updated project types to include bookmarks as an array of numbers.
