s3tables: Remove duplicate bucket extraction logic in helper

Move bucket name extraction outside the if/else block in
extractResourceOwnerAndBucket since the logic is identical for both
ResourceTypeTable and ResourceTypeBucket cases. This reduces code
duplication and improves maintainability.

The extraction pattern (parts[1] from /tables/{bucket}/...) works for
both resource types, so it's now performed once before the type-specific
metadata unmarshaling.
