UI and Backend updates (including a distance history)

[flightmansam]

Major changes:

back_airtags

• Added Devices.data
• Added distance history
  • Distance travelled in 24hours is stored (in ram)
  • Distance since last update is also stored

front_airtags

• Fixes for phone version (if width < 768px).
  • Scrollable air item list if many devices.
  • collapsed state can be removed (todo)
• Clustering of tags if within a 100px
• UI changes to remove redundant information in Popup
• initial map moves to centroid of all points (and bounds)
• Changed date to be human readable 'since' e.g. Just now, minutes ago)
• Changed air button on click to be a fly-to
• Fixed emoji of marker to match that of airlist

Tested and functional? I don't have a Mac or Airtags to test at the moment.

Of course friend! I am currently working to add Telegram bot support to send you a message if your device has moved (each device can be added on a watchlist with the back api).

I can paste a demo of the PR here by making some fake data.
