   ## Problem
   
   When compacting (or otherwise writing metadata for) an Iceberg table that has
   `Timestamptz` or `TimestamptzNs` columns, the Glue catalog schema serializer
   returns `FeatureUnsupported`:
   
   ```
   FeatureUnsupported => Conversion from Timestamptz is not supported
   ```
   
   This error surfaces in `iceberg_compaction_core::compaction` at the commit
   phase — after all data files have already been successfully rewritten — 
making
   the entire operation fail and the rewrite work wasted.
   
   Root cause: `GlueSchemaBuilder::primitive()` in
   `crates/catalog/glue/src/schema.rs` has no match arms for
   `PrimitiveType::Timestamptz` and `PrimitiveType::TimestamptzNs`, so they fall
   through to an explicit `FeatureUnsupported` error.
   
   ## Fix
   
   Map `Timestamptz` → `"timestamp"` and `TimestamptzNs` → `"timestamp_ns"`,
   matching the behaviour of Spark's Glue catalog integration which also drops
   timezone information when serializing to Glue's type system (Glue has no
   timezone-aware timestamp type).
   
   A regression test is added covering both new mappings.
   
   ## Testing
   
   ```
   cargo test -p iceberg-catalog-glue
   ```
