Improve error handling for vacuum clean_area

[arturpragacz]

Proposed change

Improve error handling for vacuum clean_area.

Improve error handling for vacuum.clean_area by utilising batched entity service call, allowing areas to be validated across all targeted vacuums at once and raising an error when areas are not mapped to any segments on the targeted vacuums.

Requires #168175.

Pull request overview

This PR improves vacuum.clean_area validation by switching the service implementation to a batched entity-service call so requested areas can be validated across all targeted vacuums, and by introducing a new translated validation error when areas aren’t mapped to any segments on the targeted vacuums.

Changes:

• Add a batched mode to entity-service registration/calling so a service handler can receive all matched entities at once.
• Update vacuum.clean_area to run as a batched service handler and raise a new areas_not_mapped validation error when appropriate.
• Extend vacuum tests and translations to cover the new error path.
