Improve data analysis part in the kit page

[oscgonfer]

This issue is to track new changes for improving front-end to better analyse data for future projects:

• [ ] Use of sensor_tags
• [ ] Link to dashboard.smartcitizen.me (?)
• [ ] Links to documentation snippets to better understand the data (which exploits the more modular way it is built now)
• [ ] Insights with averages, max/min, std...
• [ ] Insights based in the number of total readings and comp over days using count i.e. https://api.smartcitizen.me/v0/devices/14564/readings?function=count&rollup=1d&sensor_id=14 or https://api.smartcitizen.me/v0/devices/14564/readings?function=count&rollup=5y&sensor_id=14
