feat: Support sorting and re-ordering

[mstewart14]

Is your feature request related to a problem? Please describe.
Currently the order of services appearing on the main page is the order in which the items were added to the configuration file. If I want to change the order I need to take a copy of the configuration file and muck about (risking breaking it) and put it back.

Describe the solution you'd like
Wouldn't it be cool if you could drag and drop the cards on the main page to re-order things? A preset sort I can see some wanting is most recently updated vs oldest updated (either ASC or DESC depends on the individual). I'd like to arbitrarily order them based on my own view of importance. Most important at the top... least important at the bottom (possibly off screen as I have too many to fit on one screen)

Describe alternatives you've considered
only presets, order by alpha name, updated deployment date, updated source date, added date (config file order as it is now) ASC or DESC

Additional context
This is an awesome and handy tool. Now that I've discovered the regex templating system it's even more useful. Thank you for all the work put in to this.

Hello,

Adding tags on service should be very useful. The tag can help to search, order etc…
