   Fixes #18111.
   
   Truncating `Integer.MAX_VALUE - 1` with width `Integer.MAX_VALUE` currently 
produces a negative partition key. A scan filtered by `id >= 0` then omits the 
matching file.
   
   Use `Math.floorMod` in the int and narrow-integer helpers to avoid 
overflowing the intermediate remainder-plus-width addition. This preserves 
public APIs and existing behavior when the final mathematical result is outside 
the target type's range.
   
   Validation on JDK 17:
   - Full `:iceberg-api:test` suite and targeted core truncation and table scan 
regressions passed. The new regressions failed before the fix.
   - `:iceberg-api:spotlessCheck :iceberg-core:spotlessCheck` passed.
   - `:iceberg-api:revapi :iceberg-core:revapi` passed.
