feat: add a global toolbox in browser (#2160)

fix #2097
cf #1500


![image](https://github.com/user-attachments/assets/2c8b96e4-8cf7-4d5f-afed-11adf73e98a8)

This is an alternative proposal for #2097:

- adding the button near the "Filter" toggle was a bit ugly, CSS/HTML
talking, because this "Filters" box is a details/summary
- I thought that other needs could live in the same place: a link to
download the filtered/visible data, and a button to show the map data
extent

The "toggle all" button works this way:
- if one or more layers are shown, it will hide those layers
- otherwise it will show all layers

I've preferred not to change the button icon according to map state,
because I didn't find a reliable way to do so, thus I'm afraid to have
inconsistency, but I can't try harder if needed.

Related: I'm thinking of adding a "Download" button for each layers, as
it's a request that comes quite often.

@Aurelie-Jallut could you have a look ? :)
