test(sqlite): build the symbol-codec stub on a SQLite codec registry

SqliteControlAdapter takes a SqliteCodecRegistry, so the structured-error
DDL test composes its stub over createSqliteBuiltinCodecLookup() and
overrides only get(). The DDL default-rendering path reads codecs through
get() alone, so the exercised behavior is unchanged.
