Background generation (based on WorkManager API) (#228)

* Prototype WorkManager implementation

* - Beta Work manager implementation
- Local Diffusion VAE memory leak fix
- core notification & localization infra

* Stable (kind of) work manager implementation

* Introduce start notification, optimize work scheduling

* Optimize presentation module resources

* Resolve merge conflicts

* Add some Unit Tests

* Fix i2i form gallery input

* Selection toggle
