feat!: generalize script by removing organizational metadata

Remove Phase class, organizational metadata blocks, and unused project fields. Update configuration
to use 'default_grants' and simplify PI usage to fallback corresponding author determination only.

BREAKING CHANGES: - Remove 'phase' and 'project' fields from configuration - Use 'default_grants'
instead of 'default_grant' - Generate only standard Dataverse citation metadata
