Better UX - Make the listing cards more simple

**Is your feature request related to a problem? Please describe.**

I don't like how cluttered the listing cards are with information. E.g. proposal cards or process cards, why do we need to show so many things on the cards? Such as how many people are following it, when it was created, etc. And with the process cards we are showing 3 dates: start date, end date and creation date (which by the way does not have a label).

Is the user really interested in all this? Especially the follows section is quite obfuscated in case the user is already following the participatory space. Why do we even show this to the user if they are already following it? And the button says "you are already following..." and then when you click it, it states "stop following". Even I would find it hard to understand if I didn't use Decidim before. **Describe the solution you'd like**

Remove all unnecessary details from the cards. E.g. proposal card we are only interested about:

• Proposal title
• Proposal description
• Possibly: number of comments
• Possibly: number of supports (when supports are enabled)

On the process cards I'm interested about:

• Process title
• Process description

Cluttering these elements with a lot of information brings many accessibility issues, not only visually confusing but also confusing for the screen reader users. Most of this information does not need to be always visible on the cards.

**Describe alternatives you've considered**

Just hide most of the additional details on the cards. **Additional context**

In some cases it can be justified to show some extra information, such as the meeting dates. However, with proposals, processes, etc. we're not generally that interested in those dates that they would have to be shown on the cards. Users can still get that information on the process pages. **Does this issue could impact on users private data?**

Nope.
