scouting: Deduplicate action definitions in entry.component.ts

I found it tedious to keep the definitions up-to-date between the .fbs
file and the entry.component.ts file. This patch fixes the issue by
using the generated flatbuffer types everywhere.

I added a helper library to deal with `actionTakenType` properly.
Otherwise the user would have to deal with it manually.

Since Angular templates don't seem to allow manual type casting, I
created a pipe to do it for me.
