Entities with verbatim chunks do not appear in admin space

[OlivierHecart]

Describe the bug

Entities with verbatim chunks, i.e: a subscriber on @zetta/fr should appear in the admin space under key @/<zid>/router/subscriber/@zetta/fr but does not.
It does not appear in replies to a query on @/<zid>/router/subscriber/**. This is expected as @/<zid>/router/subscriber/@zetta/fr does not match @/<zid>/router/subscriber/**.
It does not appear in replies to a query on @/<zid>/router/subscriber/@zetta/fr. The problem here is that @/<zid>/router/subscriber/@zetta/fr does not match the admin space @/<zid>/router/** and so is not routed to it.

I see 2 potential solutions:

• Add a 'super wildcard' in the key expr '$' dsl.
• Implement, as we already discussed internally for other reasons, an admin space specific routing that would mitigate this issue.

To reproduce

> zenohd
> z_sub -k @zetta/fr
> z_get @/*/router/subscriber/@zetta/fr
