Refactor wecker.sh script

Made the following changes to the wecker.sh script:
- Adjusted comments and translated the comments and script messages into English for better clarity.
- Introduced error handling for SSH commands, Bluetooth operations, and volume adjustments to ensure the script exits gracefully in case of failures.
- Updated variable names for consistency and improved overall readability of the script.
- Removed unnecessary debug-related code and streamlined the script structure.
- Addressed formatting issues for better code presentation.
