Glue doesn't support the purge option when dropping tables, returning a
400 error immediately, even after the underlying table has been dropped:
```
WARN 2025-08-08 19:00:21,698 [shard 0:main] iceberg - catalog_client.cc:367 - [/iceberg/v1/catalogs/12345/namespaces/redpanda/tables/table?purgeRequested=true] error: http_call_error: Bad Request, message: '{"error":{"code":400,"message":"PurgeRequested cannot be true for Glue iceberg tables.","type":"InvalidInputException"}}'
```
When in this state, translation for this topic and all other topics of
the same name is stuck indefinitely, because when
redpanda.iceberg.delete is true, we will try to drop the table of older
versions of the topic before allowing creation of the new table.
This commit adds a stop-gap to at least be able to get unstuck by
manually deleting the table. When dropping, we'll first check if the
dropped table has been deleted already.
Redshift complains when using an null 'partitions' field in the manifest list: ``` ERROR: Wrong type in Avro file. Detail: ----------------------------------------------- error: Wrong type in Avro file. code: 15003 context: Field: partitions. Expected: 12. Got: 7 query: -1[child_sequence:1] location: avro_utils.hpp:55 process: padbmaster [pid=1073913955] ----------------------------------------------- [ErrorId: 1-68963282-20644b700a198f806702f6aa] ``` This fix has Redpanda serialize empty 'partitions' as an empty array. Tested manually against Glue and Redshift.

We will need follow-up work to allow for topic deletion to not require manual intervention. This at least allows a cluster to become functional after the Iceberg topic has already been deleted.
