A table on a backend module with no query interface (a storage-only
module such as qbit-edi's edi_preview_download) was classified DATA,
read by the keyset pager, and failed the whole run with
"IllegalStateException: Query is not implemented in this module".
TableRoles.isQueryable() now resolves the module through
QBackendModuleDispatcher (cached per backend type) and such tables are
EXTERNAL and always excluded by ScopeResolver with reason NOT_QUERYABLE,
even when selected by name or role. The Run backup review lists them,
and no per-table export process is offered for them.
Failed runs now persist "Backup failed: Class: message" in error_message
and the class, cause chain and top root-cause frames (bounded to 8 KB)
in error_detail, both sanitized by the new FailureText (URL user-info,
presigned query parameters, key=value secrets, Authorization/Bearer
values, AWS access key ids, PEM blocks and Postgres row values are
redacted; object keys and bucket names are kept).
