### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary:
The File Scanner V1 Iceberg reader accepted equality delete metadata with an
empty field ID list. That allowed malformed metadata to reach a zero-column
equality comparison, where every row could compare equal.
This change rejects missing or empty equality delete field IDs at the reader
entry point, matching the File Scanner V2 invariant. It also adds a BE unit
test that verifies rejection happens before delete-file I/O.
### Release note
Reject malformed Iceberg equality delete files with no field IDs.
