#946 and #947

This pull request introduces improvements to the service editing workflow, focusing on better handling of file cleanup during service renaming and enhancements to the multi-choice question payload logic. The main changes ensure that outdated files are properly deleted when a service is renamed and that payloads for multi-choice questions are generated more accurately.

File management improvements during service edits:

• Added a step to delete old MCQ-related files by calling the file manager service before proceeding to delete all MCQ files in the edit.yml workflow.
• Enhanced the structure update flow to check if the service name has changed, and if so, delete the old main file before proceeding with the edit.

Multi-choice question payload logic:

• Updated the handleMultiChoiceQuestion function to more robustly generate payloads for multi-choice question buttons by extracting the root service name, ensuring payloads are correctly formed after renaming.
