Add MiniGrid overview page and update map routes.

[Kiwumulo-Nickson]

Brief summary of the change made

Resolves: #130

#Created MiniGridDashboard.vue component — similar to AgentDashboard.vue:

Metrics boxes: Total Mini-Grids, Total Clusters, Total Cities, Total Agents

Searchable table listing all mini-grids
Columns: Name, Cluster, Created At, Cities, Agents

Clickable rows navigate to the detail page

#Refresh button to reload data

#Updated pages/Dashboard/MiniGrid/index.vue:

#Replaced the redirect logic with the new MiniGridDashboard component which matches the Agents overview page structure.

#Added translation keys to en.json:
miniGridDashboard: "Mini-Grid Overview"
miniGridList: "Mini-Grid List"
totalMiniGrids: "Total Mini-Grids"
totalClusters: "Total Clusters"
totalCities: "Total Cities"

#The component handles missing API data (e.g., cities_count, agents_count, cluster) and displays "-" or 0 when unavailable. The overview page now shows a list of mini-grids in a table format, matching the Agents overview page pattern, instead of using a dropdown menu.

Are there any other side effects of this change that we should be aware of?

Hey @Kiwumulo-Nickson You still have some merge conflicts here. Also, more leftovers from the Africa's Talking docs. Could you clean up both of these?

I think there is some Syntax error here. MiniGridDashboard is not imported anywhere.
