[feature] Add a dedicated page for showing devices on the map

[pandafy]

The goal is to add a dedicated view for viewing devices on the map. We have such a map on the dashboard, but it's size constraints (due to other UI elements) affects it's usability.

A dedicated page for using viewing all the devices on map would elevate such UX constraints.

This is a rough idea of what we want to achieve

Sir @pandafy , Guidance Needed for Resolving Setup and Runtime Issues

I’m working on setting up and running the monitoring project but I'm facing a few challenges.

Where in the openwisp_monitoring module should I add the feature?
Are there specific conventions or test updates required?

Database Locked Error:
I encountered django.db.utils.OperationalError: database is locked.

Accessing the Project Locally:
After accessing the login page at http://localhost:8000, what credentials should I use?
If no admin account exists, should I create one using createsuperuser?

Project Workflow:
What should I validate or test after logging in to ensure my feature works as intended?

Could you provide tips for debugging and integrating features effectively?
I would be thankful for what you do a slightly advise me to solve these things.

I love contributing to this organization, which makes me feel confident in my knowledge of the tech stack, most of which is related to your codebase
