feat(cloud): Add custom cloud API URL configuration support (#181)

* feat(cloud): Add custom cloud API URL configuration support

- Implement RPC methods to set, get, and reset cloud URL
- Update cloud registration to remove hardcoded cloud API URL
- Modify UI to allow configuring custom cloud API URL in developer settings
- Remove environment-specific cloud configuration files
- Simplify cloud URL configuration in UI config

* fix(ui): Update cloud app URL to production environment in device mode

* refactor(ui): Remove SIGNAL_API env & Rename to DEVICE_API to make clear distinction between  CLOUD_API and DEVICE_API.

* feat(ui): Only show Cloud API URL Change on device mode

* fix(cloud): Don't override the CloudURL on deregistration from the cloud.
