* Add friendly names for system services
- Adds a $service_friendly_names array at the top of the details block
- For each service, tries to find a match in the array and sets the $display_name
- If no match found in the array, it falls back to prettifying the name automatically (replace underscore with space and capitalize the first letter of each word) so future services don't break the display
* Updated system_services card with more info
- Expanded the system_services card with an additional column for 'Runtime', showing how long the service has been running for
- Added a hover tooltip showing the PID of the service to all three columns
- Added the ability to fetch for additional services string from default settings to show in the system_services card
* system_services dashboard card new default setting
- Added a new default setting (theme -> dashboard_extra_system_services) for defining additional system services to monitor in the system_services dashboard card
- Default setting is enabled by default with a string value of 'freeswitch, nginx, postgresql, sshd'
* Adjusted column widths
