Latency quantiles

You can now refine your latency data more effectively with quantiles: p99, p95, p90, and p75. The average (avg) has been retained.

The <Tracker /> data on your status pages now displays the p95 quantile instead of the average.

Furthermore, the /monitors layout has been updated. The data table has its dedicated tab to prevent loading excessive data at once, along with the edit form. The pause button is also now more quickly accessible.
