#119 assira.ui: trivial dependency injection

more or less we want to standardize injection inside assira.ui models, controllers etc

- [x] we created `HostContext` implementations for bean discovery. - [x] we created `TypeMap` for type match. - [ ] we need to create constructor matcher: iterate through arguments and for each argument type match bean from HostContext - [ ] do we want to support multiple constructors? https://github.com/spring-projects/spring-boot/issues/17455
