Implement Withdraw Endpoint for Issuance Offers

[nanderstabel]

Description

While the addition of the Withdrawn status to the Status enum is covered in another issue (#119), this task focuses on adding the API endpoint to allow users to withdraw an offer.

Add a /v0/offers/<offer_id>/withdraw endpoint which can be called to withdraw a Credential Offer.

• Create a new command to handle the withdrawal of an offer, triggering the appropriate event that updates the offer's status to Withdrawn.

• Update the OfferView to exclude withdrawn offers from the active offers list presented to users.

Motivation

Users will no longer see the withdrawn offers in their active list, reducing confusion.
