Implement proper error handling mechanism

[aniri]

Implement an easy to use error handling mechanism.

Should support displaying snackbars and dialogs. Check the design in Figma for hints on how to design them, but follow the android material design guidelines for them.

These should be displayed easily in case of validation or api errors.

Redirect to login in case auth errors are received from the api. The rest of the api errors should be displayed in a dialog. TBD: api error format

Also, for certain requests, a snackbar error should be shown in case the user attempts to make the api call but is not connected to the internet.

@ClaudiuBogdan thanks for the tips! It would be great to have a unified way of showing App errors, that could be reused in the application. Most importantly for auth and other api errors :)

Sure, I'm just adding reference documentation for the implementation.
