[Enhancement] Add an Option to Replace Images Instead of Deleting in Frontend Post Creation/Editing

[anik-fahmid]

Description: When updating a post with a new image, the old image is automatically deleted from the server. Users would prefer a "replace" option that allows the new image to overwrite the old one without automatically deleting the existing image from the server.

The request is to add a Replace button on the image upload field during post-editing/post creating to provide flexibility to retain the old image on the server.

The issue arises during both the creation and editing of posts through the WPUF frontend.

Expected Behavior:

• When a user creates/updates a post with a new photo, they should have both the options:
  1. Replace the old photo (keeping the old one on the server).
  2. Delete the old photo as it is now.
