Review Comment:
Ah all the logic in this class shouldn't even need to be defined for
`SparkCatalog`, I think I can safely remove all this.
We'll never access this code path in the current implementation of
compaction; compaction has an inherent expectation that the task group being
compacted has a reference in the `SparkTableCache`, and as a result compaction
will always internally use the `SparkCachingCatalog`.
https://github.com/apache/iceberg/blob/main/spark/v4.0/spark/src/main/java/org/apache/iceberg/spark/actions/SparkDataFileRewriteRunner.java#L49
The prefix matching being done here should only be for identifiers that are
publicly facing users but for compaction it'll look something like `<compaction
groupId>#rewrite`. where the group ID is something we assign internally and
isn't expected that a user should directly try to reference
