fix: few UI ideas

[jy95]

Hello,

I'm come up with few ideas to increase the UX :

• Use tooltip (infobulle in french) for too-longs tags

If a tag string length is above X (let's say 50 characters), a tooltip to display the full text (when we are hover this tag) is useful.
Currently, some tags are too long (it could occur for other reasons like a long course name)

• Use "rectangle with rounded corners" containers around tags for the ones inside "favories" and "historique" panels

Currently, we have something like that :

The | symbol may be not clear enough for some cases (like many tag , etc...) so why not reuse the same tag container and the same color used in the main search (except that here there is not cross to remove the tag like the main search)

Of course, because some tags have long, we could combine this idea with the previous one (the tooltip)

• Remove "Nb de" for url /administration/categories :

With the context, I don't believe it is useful to prepend "Nb de" (nombre de) in the columns titles as it seems easy to understand
