[frontend][backend] List custom views in settings (#13389)

[fellowseb]

Proposed changes

Implements chunk Settings: an administrator is able to see listed custom views for an entity type of the "Custom views" feature

A custom view is a dashboard an administrator creates for a given entity type. This dashboard is then viewable (not editable) by "normal" users.

User journeys

• Case 1: for Entity Types that are eligible to having Custom Views, given there are custom views in the database, when an admin goes to Settings > Customization > [Entity type] a "Custom views" section is displayed and lists the views already created.
• Case 2: for Entity Types that are eligible to having Custom Views, given there are no custom views in the database, when an admin goes to Settings > Customization > [Entity type] a "Custom views" section is displayed and displays "No items available".
• Case 3: for Entity Types that are NOT eligible to having Custom Views, when an admin goes to Settings > Customization > [Entity type] no "Custom views" section is displayed.
• Case 4: non admins don't have access to the Customization page
