Allows contact managers to export and import contacts from the Contacts
page while keeping plain agents blocked. The contacts action menu now
mirrors backend permissions for both export and import.
## Closes
- https://linear.app/chatwoot/issue/CW-4438/contact-export-is-broken
## What changed
- Allows Enterprise custom roles with `contact_manage` to pass
`ContactPolicy#export?` and `ContactPolicy#import?`.
- Shows Export and Import to admins and contact managers only.
- Adds Enterprise policy coverage for contact export and import.
## Screenshots

## How to test
- Sign in as an administrator and open Contacts; the action menu shows
Export and Import.
- Sign in as a custom-role user with `contact_manage`; the action menu
shows Export and Import.
- Sign in as a plain agent; Export and Import are not available and both
APIs remain unauthorized.
