refactor: improve package layout to enforce data, domain and ui packages

Description

The MR is quite complicated to review, so I made a sumup here.

This MR improves package layout to enforce data, domain and ui packages at root.

1. di package has been split into: data/di/bindings, data/di/db, data/di/system, data/di/network, data/di/qualifiers, ui/di, ui/navigation
2. microg has been moved to data/microg
3. provider has been moved to data/provider
4. receiver has been moved to data/receiver
5. utils has been split into: data/system, data/utils, data/exodus, data/event, ui/utils, ui/extensions
