feat(daemon): modernize daemon logging with tables and color-coded output

- Modernize periodic status update with logger.logTable() and color-coded battery/runtime
- Modernize configuration loaded display with tables for UPS devices and groups
- Enhance power status change notifications with better colors and timestamps
- Modernize shutdown monitoring with real-time table display of UPS status
- Add color-coded CRITICAL indicators for emergency conditions
- Improve visual hierarchy with appropriate box styles (info, warning, error, success)
- Ensure consistent theming across all daemon log output
