Fix Tasks/Notes created with null position (#9068)

Fixes https://github.com/twentyhq/twenty/issues/8810
Fixes https://github.com/twentyhq/twenty/issues/5268
Fixes https://github.com/twentyhq/twenty/issues/8971

- Fixing Task/Note creation not sending position during creation
- Adding a command to backfill position being null, using existing
backfill command.
- Removed unused backfill job.
- Updated workspace entities to set position non-nullable and set a
default value to make it non-required on the API
- Updated position factory to set a default position for all objects
having a POSITION field instead of only company/people
- Moved the try/catch in each resolver factory calling
GraphqlQueryRunnerException handler, makes more sense to call it in the
actual graphql-query-runner and removing some duplicate codes
- Adding validations for input in QueryRunnerArgs factories
- Allow sync-metadata to override and sync defaultValues for certain
field types (that can't be updated by users)
- Removing health-check from sync-metadata command during force mode to
improve performances
