Did you run make format && make check?
The go code was not changed. npm run lint and npm run build were used.

Changes:

• Code for managing the modal window state was added in parts that did not have it.
• The code for keeping the node data updated was removed from NodeService and 2 new services were created with similar functionality, but much simpler code, as the old code was virtually unmaintainable and the current structure of the app do no needs it centralized. This will allow to make future changes.
• Other small code improvements.

How to test this PR:

• The modal windows for configuring the password for the first time and for configuring the vpn client app should not allow to do anything while an opperation is in progress.
• Navigating between the visor list and the visor details page should work as before and the app should now respond a bit quicker if navigating rapidly between de details pages of several visors.
