Pull request overview

Updates Varien_Data_Collection_Db’s $_map PHPDoc to reflect its real runtime structure (including Zend_Db_Expr mappings) and adjusts addFilterToMap() initialization logic to avoid accessing an undefined group key. The PHPStan baseline is updated accordingly by removing now-unneeded ignores.

Changes:

• Broadened $_map property type from a fixed fields-only shape to a generic group map that supports string|Zend_Db_Expr values.
• Replaced a potentially undefined-offset null check with an array_key_exists() group presence check in addFilterToMap().
• Removed PHPStan baseline suppressions that were only required due to the previous $_map type.
