feat: Add base HTML template and implement dashboard, logs, and service views
- Created a base HTML template for consistent layout across pages. - Developed a dashboard page to display backup service metrics and statuses. - Implemented a log viewer for detailed log file inspection. - Added error handling page for better user experience during failures. - Introduced service detail page to show specific service metrics and actions. - Enhanced log filtering and viewing capabilities. - Integrated auto-refresh functionality for real-time updates on metrics. - Created integration and unit test scripts for backup metrics functionality.

# This is an example showing how to integrate the simplified metrics system

# into the existing Plex backup script for basic status tracking.
|

#
|
||||
# The modifications show the minimal changes needed to add metrics tracking
|
||||
# to any backup script.
