[IMP] Complex dashboard

This dashboard adds more statistics and styles to look like a professional IoT dashboard.
Also, data is retrieved from database. Anyway, its pretended change that behavior to livewire components to make real time dashboard.

* [IMP] Remove header from dashboard
* [ADD] Board boxes status examples
* [ADD] No active sessions registered and styles
* [ADD] Change link boxes to statistics section
* [ADD] Statistics boxes (not finished)
* [FIX] Measurements seeder was creating just 5 session entries. Fixed to all sessions
* [ADD] Show last 4 boards with most recent activity
* [ADD] Statistics boxes with data database information
* [IMP] Statistics colors and styles
