Clean orphan metadata (#16914)

# Introduction
Followup https://github.com/twentyhq/twenty/pull/16863

Important note: This is not an upgrade command and will have to be
manually run

In this pull request we're introducing a coding that will allow this
[migration](https://github.com/twentyhq/twenty/blob/clean-orphan-metadata/packages/twenty-server/src/database/typeorm/core/migrations/utils/1767002571103-addWorkspaceForeignKeys.util.ts#L3)
to pass, it enforces the `workspaceId` foreignKey on all metadata
entities. Allowing workspace deletion cascading of all its related
entities and avoiding orphan metadata entities to reoccur in the future

Also introduced a small migration that will set the workspaceId col type
to `uuid`, as it has been historically `varchar`
This migration is a requirement for the above command to work
successfully


## Note
Chunking by relations fields the orphan field deletion as would take way
too much time within a transac,

## Test
Tested on a prod extract locally ( both dry and not dry )
