[APM] Dashboards tab when user does not have edit permissions to saved objects

[crespocarlos]

Summary

We should hide the dashboards tab or display a message when users don't have edit permissions to saved objects

User without edit permission to saved objects

Steps to reproduce

Stateful

• Create a user with elasticsearch index privileges:
  • indices: metrics-apm,apm,traces-apm,logs-apm
  • privileges: 'read', 'view_index_metadata'
  • and kibana privileges: APM and User Experience
• Navigate to APM Service Overview
• Click on the Dashboards tab

Serverless

• Login with a user with Viewer role
• Navigate to Applications / Services and click on a service
• Click on the Dashboards tab

Possible solution

This is what Infra does when capabilities.savedObjectsManagement.edit is false

Make sure to do the same for the Dashboard tab on the Multi Signal Service Overview
