(fix): resolve Structure validator missing Float, TenantFilter alias check, and Document tenant type cast

- Add ColumnType::Float case to Structure validator switch (falls through to Double handling)
- Pass actual collection name to TenantFilter so metadata check uses the real table name instead of the query alias
- Remove int cast in Document::getTenant() to prevent strict comparison mismatches with Adapter::getTenant()
