Redesign the main dashboard to be more welcoming, informative and faster

[anna-geller]

Planned changes to the main dashboard:

• Keep the top chart but label the axis + add a description of the legend on the top
• Change the pie charts into a number/KPI with an upward/downward trend at the top
• Change the colors and add labels
• Clearly include information about currently running and scheduled executions
• Remove the error logs per namespace and the large table
  

Context

The main dashboard currently suffers from the following issues:

1. When new users get started, they tend to make mistakes, and seeing a red dashboard isn't encouraging. -> Change the colors to be on-brand and color-blind-friendly

2. The charts in the middle take too much space for the limited amount of information they provide -> change to numbers with a trend:

3. Tables with error logs and recently failed executions are slow to load -> remove them:
   

4. There are two tree maps that display the same information -> remove them:

5. The colors are not color-blind friendly and "boring" :) We can enliven it with kestra-specific colors

6. Axis are missing labels and the legend is missing to explain what is meant by each color

We want to redesign this main dashboard.

Preferred visualization types:

• numbers with upward/downward trend
• line chart
• area chart
• (grouped) bar chart
• scatterplot
• if REALLY needed, a pie chart (best to avoid)
