Fix and refactor all metadata relation (#17978)
# Introduction
The initial motivation was that in the workspace migration create action
some universal foreign key aggregators weren't correctly deleted before
returned due to constant missconfiguration

/>
It also meant that under the hood some optimistic behavior wasn't
correctly rendered for some aggregators

## Solution
Refactored the `ALL_METADATA_RELATIONS` as follows:

This way we can infer the FK and transpile it to a universalFK, also the
aggregators are one to one instead of one versus all available
Making the only manual configuration to be defined the `foreignKey` and
`inverseOneToManyProperty`
