HOTFIX: Fix duplicate collectionSlug field error

- Multiple step types (create-document, read-document, etc.) were defining collectionSlug fields
- These created duplicate field names at the same level in the Workflow collection
- Fixed by prefixing step field names with step slug (__step_{stepSlug}_{fieldName})
- Added virtual field hooks to store/retrieve data using original field names
- Resolves DuplicateFieldName error preventing PayloadCMS initialization

Fixes: #duplicate-field-name-issue
Closes: User bug report for @xtr-dev/payload-automation@0.0.30
