Function humanize_or_debug

src/sql/src/plan/query.rs:5199–5203

Returns a human-readable rendering of `name`, falling back to a debug dump of the `ResolvedItemName` if humanization fails. Used to construct user-facing error messages on already-failing paths, where we'd rather surface the raw resolved name than emit a useless ` ` placeholder.
