s3tables: fix pagination and enhance error handling in list/delete operations

- Fix InclusiveStartFrom logic to ensure exclusive start on continued pages
- Prevent duplicates in bucket, namespace, and table listings
- Fail fast on listing errors during bucket and namespace deletion
- Stop swallowing errors in handleListTables and return proper HTTP error responses
