Some invalid journal data is now handled
Journals now use polymorphic deserialization
Added Event names to all journal events
Remove unused controllers
Refactored out the logic backing the JournalBase TimestampDateTime property so it can be used for any DateTime type property, providing a standardized json String -> DateTime conversion for any date-time property. Implemented as an `internal static` method on JournalBase so journal objects which inherit from JournalBase or don't inherit from it can use it.
Used this to provide a DepatureTimeDateTime on CarrierJumpRequest (this property was added in Update 14) and to implement the existing ExpiryDateTime on CurrentGoal.
From a quick search in the journal documentation, I don't see any other applications for this.
* chore: move all observatory repos to core
* only save journal folder on change, don't constantly re-check during monitoring
* chore: monorepo project changes
* chore: monorepo migration
