Fix aspect ratio limitation for long videos

[BSoDium]

This pull request introduces several enhancements to the development workflow, improves video handling in Telegram sync, and refactors authentication code for clarity and maintainability. The most significant changes include adding a devcontainer for a streamlined development environment, improving how video metadata is extracted and sent to Telegram, and refactoring authentication token handling.

Development Environment Improvements:

• Added a .devcontainer/devcontainer.json file to enable development in a standardized containerized environment, including Python and debugging extensions, and a post-create command to install dependencies.
• Refactored the Dockerfile to use multi-stage builds for separate production and development images, and updated compose.yml to build using the production target. [1] [2]

Video Metadata Extraction and Telegram Sync:

• Added a new get_video_metadata function in tools.py to extract width, height, and duration from MP4 video bytes using ffprobe, and integrated it into telegram_sync.py to send videos to Telegram with accurate metadata (width, height, duration). [1] [2] [3]

Authentication and Code Quality Improvements:

• Refactored google_auth_wrapper.py to import authentication constants and utility functions directly, improving readability and maintainability. Enhanced error handling for homegraph responses and improved logging by using a censor function for access tokens. [1] [2] [3] [4] [5]

VSCode Workspace Enhancements:

• Updated google-nest-telegram-sync.code-workspace to add a debug configuration for main.py and included the new devuser in spellchecker settings.
