[MVP Carry-Over] UpdateItem List Pages

0. Remove UpdateItem List from User Profile page
1. The list of update_items submitted to date is visible to a logged-in user in a different tab.
2. This list can be filtered and sorted based on some of the attributes like "user_id", "status", "entity", "timestamp" etc.
3. Maintainers always have the option to change the status of a update_item to "accepted" or "rejected". This option is no more available once the status is "synced.

Maintainer sees

• Updates submitted by all users
• Heading of the page is "All submitted changes"
• Can change the status of particular record and "review comments"

Contributor sees

• Updates submitted by only them
• Heading of the page is "My submitted changes"

P.S.: The similar table component can be used in detail pages with an extra filter on the entity and entity_id
