Integrate custom Kiezradar deleteModal into a4

[hom3mad3]

Description:
A new delete modal has been introduced in PR #6002 (update: refactored here). To avoid functionality duplication and ensure reusability, it should be integrated into the global Modal.jsx component in the A4 codebase.

Expected Outcome:

• The delete modal should be part of the global Modal.jsx.
• Ensure that it can be reused wherever necessary across the application.

Tasks:

• Review the current delete modal implementation from PR [#8813] Add kiezradar delete modal #6002.
• Refactor the delete modal code using the global Modal.jsx component in a4 (like ReportModal.jsx etc).
• Delete instances of deleteModal and custom styles (instead use a4-modal.scss)
• Ensure existing modal functionalities are preserved and consistent.

Additional Notes:

• Check for potential conflicts with existing modal usages.
• Confirm that UI/UX remains consistent post-integration.

@hom3mad3 if you say this is low prio, can it be done after release? If not, please add to milestone "fix before re-launch"

@CarolingerSeilchenspringer it can be done after release, but i moved to medium since it's important nonetheless

[CarolingerSeilchenspringer]

@hom3mad3 our definition of medium is to be fixed before next release, so I put to low but into the milestone that we will check after release. :-)
