feat(directory): Add service to cart from service details page

[connoratrug]

Issue

If a user moves from the cards view to the service detail view its nice if the user can decide to add/remove the service directly form the details view ( instead of going back to the card). This is also consistent with the adding/removing of the collections

Solution

add a add/remove button on the service details page and link it to the cart

Alternatives

do nothing, services can still be added/removed just takes more clicks and is less consistent

Additional context

The directory app model was updated so the user can now request services
