added button in nav bar for kanban view (twentyhq#6829)

@Bonapara 
Addressing issue twentyhq#6783.
 
I tried to achieve the exact behavior you were looking for, but I
couldn't get the dropdown to render correctly in that specific column.
I'd love some help to make sure it's working as expected! 😊
Most of the logic is shared with the `useHandleOpportunity` and
`useAddNewCard` hooks, which could be refactored to reduce code debt.
Also, please go harsh with the review because I know there's a lot of
code cleaning required.
I also agree with Charles's point in [this
comment](twentyhq#6783 (comment)).
Thanks :)
