Feature: Show permissions as a separate tab (#2396)

Browse Source 
Show permissions as a separate tab

- Move permissions code into a separate for better readability and maintainability.
- Separate `Permissions` node from `Encryption` so that it would be displayed in the frontend as a separate tab.
- Use more user friendly permission labels such as replacing `canModify` with `Modifying` and values such as `Allowed` and `Not Allowed` instead of `true`, `false`.
- Show permissions regardless of the encryption state.
