Create dashboard page

[DennisAlund]

Description

Create a simple dashboard as a landing page for the CMS.

1. Update the sidebar menu

• The dashboard menu items should not be a dropdown.
• Remove the eCommerce option
• Clicking dashboard menu item should be the landing page of the CMS

3. Create a simple post type counter

This is the only element on the dashboard. Use the following element template

• Read content types from firestore path: /tanam/tanam-testing/document-types
• Count how many posts are of each type by using aggregate queries
• Count the documents by querying firestore path: /tanam/tanam-testing/documents on their attribute documentType to match the document id in document-types

Create two tables on the dashboard page

1. List of most recently created documents
2. List of all document types and a counter for how many documents exist of that type (aggregation query)
