Bootstrap backoffice suite

We need to monitor on how the service is used and/or help our customers to solve issues (impersonate, extend trial, etc.).

For the beginning, need to decide what to use: inertia with the same UI we use for frontend OR filament OR something else.

Implement basic users list view.

Implement the team list view, display the next data:

• Customer (with link to a customer page)
• Team Name
• Number of nodes set up
• Number of nodes alive
• Number of services

The team view (edit?) page should get a form to allow to update the team's quotas.

Unfortunately, it was quite non-trivial to make the Filament work with the JSONB fields serialized as Laravel Data objects (or it required lots of crutches), so I have decided to go with a hand-crafted solution. Oopsie. :)
