Patrik 6d768748a0 fix(plugin-import-export): csv export for polymorphic relationship fields (#12926)
### What?

Fixes CSV export support for polymorphic relationship and upload fields.

### Why?

Polymorphic fields in Payload use a `{ relationTo, value }` structure.
The previous implementation incorrectly accessed `.id` directly on the
top-level object, which caused issues depending on query depth or data
shape. This led to missing or invalid values in exported CSVs.

### How?

- Updated getCustomFieldFunctions to safely access relationTo and
value.id from polymorphic fields

- Ensured `hasMany` polymorphic fields export each related ID and
relationTo as separate CSV columns
