* chore(config)_: Integration of new RPC Provider configurations
* default_networks.go
* explicit provider initialization with more granular config (rps limiter, order)
* token overrides made more flexible, support not only infura and grove
* get_status_node.go
* override status-proxy auth instead of passing override config to rpc/client.go
* config.go
* ProviderConfig removed
* client.go
* Now any provider can be enabled/disabled (if user wants to use only his custom RPC urls)
* Use bearer auth instead of URL auth
* Provider order is defined by default_networks.go
* Do not store embedded RPC provider credentials in the DB
* FIXME: TestLoginAndMigrationsStillWorkWithExistingDesktopUser uses deprecated test data (with non-existing related_chain_id in networks table)
