Refactor log handling and add UI auto-update toggle

Browse Source 
This commit refactors the log handling in the API to use a switch statement for improved readability and maintainability. It also introduces error messages with more context when reading or truncating the log file fails.

On the frontend, a new auto-update toggle button has been added to the log viewer, allowing users to enable or disable automatic log updates. The button's appearance changes based on its state, providing a clear visual indication of whether auto-update is active. Additionally, the button styling has been updated to ensure consistency across the interface.
