Blazor cleanup

[hahn-kev]

Fixes a number of issues

• opening a project shows a blank screen for a while
• sometimes a project can show the data from the previous page that was opened
• closing FwLite desktop would not properly close FwData projects leaving a lock file in place
• closing FwLite desktop would throw an error
• fwdata changes were not always saved after every change

the main change here is the introduction of the IMiniLcmApiProvider, this is a simple class that let's the frontend await a promise which resolves to the API being injected. Usually provided by CrdtProject.razor or FwdataProject.razor. This is instead of polling for the API which was much slower and prone to bugs.

An open problem is still that if open a project and immediately go back, you will get an error due to trying to invoke functions on a disposed reference
