Don't allow viewing Site Permissions Panel for brave://wallet route

[Douglashdaniel]

Description

Previously we showed a Connected status and didn't allow viewing the Site Permissions in the panel when your current tabs origin is brave://wallet. It has regressed and needs to be fixed to not allow.
