docs(migration): Add comments explaining related field synchronization

Browse Source 
Added documentation to clarify:
- Why store=True is used for related fields (performance for filtering/searching)
- Why manual synchronization is needed in migration (related fields don't auto-sync during SQL INSERT)

No functional changes, only improved code documentation.
