Issue Description

Add a feature that allows users to request an extension on their onboarding period within the Discord server using a Discord slash command (e.g., /onboarding-extension). If a user cannot complete the required onboarding task within the set 31-day period, they automatically receive a group-onboarding31d+ tag. The user can request additional time within the last 7 days of the 31-day deadline, which will be subject to approval by superusers.

Expected Behavior

• Users who fail to complete the onboarding task within 31 days will automatically be assigned the group-onboarding31d+ tag.

• These users can request an onboarding extension only within the last 7 days of the 31-day period by typing the slash command /onboarding-extension in the server.

• Superusers can review and approve/deny the extension request via a Discord command (e.g., /approve-extension or /deny-extension).
  -Upon approval, the user's onboarding period will be extended, and they will not get the groupOnboarding31d+ tag until the extended deadline passes.

• If the extension is denied, the user will have the groupOnboarding31d+ tag, and further action will depend on superusers

Current Behavior

Currently, users get the grouponboarding31d+ tag if they do not complete the onboarding task within the 31-day period. There is no option for users to request an extension.
