Charge fixed row bookkeeping once per table and row within an admitted
metadata layout. Repeated owner lookups no longer permanently consume
capacity for temporary cursors; distinct rows and failed admissions retain
the existing representation limit and typed failure behavior.
Verify repeated local attribute-constructor lookups through public CLI
metadata/member inspection and preserve the remaining capacity guards.
Closes#1878
