feat: CSAT Response Visibility

[JeffOtano]

Description

This change creates the ability for an administrator to hide the CSAT (Customer Satisfaction Survey) result from agents.

This includes:

• New UI for the setting under inbox settings
• New DB Migration to add the field
• Limit display content attributes based on this setting and whether the viewer is an administrator

Motivation behind this change was derived from one of our users who mentioned that their Agents were complaining about poor CSAT surveys, ideally this is strictly viewed by the management (administrators)

Addresses #9447

Type of change

• [x] New feature (non-breaking change which adds functionality)

How Has This Been Tested?

This change has gone through manually testing for multiple inbox types that Rinsed uses, specifically:

• Widget CSAT Response
• Email CSAT Respone
• SMS CSAT Response
