   Closing this PR. #69723 (merged on 2026-11-02) removed the legacy file 
scanner together with the V1 Iceberg reader code this PR fixed 
(`equality_delete.cpp`, `iceberg_reader_mixin.h` and both test files), so 
nothing is left to change on master. Plans from an FE older than 4.1.4, which 
send no `iceberg_scan_semantics_version`, now go through FileScannerV2, which 
builds a missing equality-delete key as a NULL literal or an initial-default 
expression instead of repeating a one-row column. I will cover that V2 path for 
such plans (top-level, composite and nested missing keys, Parquet and ORC) in a 
follow-up test PR. The V1 defect still exists on branch-4.1 and branch-4.2 and 
is tracked separately.
