Handle access rights of reviewer in approval sequence

Description

1. Allow all kinds of changes to be applied for the IT system regardless of a reviewers' access rights after an approval sequence is approved at the last step. Reviewers need the minimum access right to access change details view. This minimum value should be Read.

2. For moving related changes:

• After a sequence is approved, the admin log should show a requester's identity as the action trigger, not a reviewer's.
• If content is moved to Trash, then "deleted by" information in trash should show requester's identity as well.
