feat: Video Editor: Add Chapters Support, Video Trimming, and Chapter Display

[Yiannistaos]

Description

This PR significantly enhances the Video Editor with three major features: video trimming capabilities, comprehensive chapters support, and chapter display in the video page. The video trimming feature allows precise editing of start and end points, optimizing content length without requiring external tools. Users can now also create, edit, and interact with video chapters directly in the player interface, providing intuitive navigation through video content. Additionally, various bug fixes and stability improvements have been implemented to ensure a robust editing experience.

Changes

• Implemented frame-accurate video trimming functionality with preview support
• Added comprehensive chapters support in edit_media with creation, editing, and deletion capabilities
• Integrated interactive chapter display and navigation in the video player interface
• Fixed multiple UI/UX bugs and improved overall Video Editor stability
• Created standalone Vite/React application in /frontend-tools/video-editor/ for improved development workflow
• Added build_and_deploy.sh script to streamline the deployment process
• Updated documentation and deployed optimized static assets

This is incredible.

Quick comment, please remove all files from static_collected . This is a path that all static files are collected when developing locally, so we don't want to commit them anyways. The PR now has 468 files :)
