fix(memory_agent): handle draft run without current release

- Add TODO comment to verify end_user sources (chat, draft, apikey)
- Comment out release validation check to support draft run mode
- Add TODO note explaining temporary fix for draft execution
- Handle null current_release_id in result by returning None instead of failing
- Improve import formatting for MemoryConfig model import statement
- Allow configuration retrieval when app has no published release
