Remove deprecated 'authority' references from tap form (#13850)

PR #13578 removes 'authority' from being a pseudo-k8s resource, but the
viz web `/tap` form still expects it to be present, issuing a
`/api/tps-reports?resource_type=authority&all_namespaces=true` call, which
returns 500 `cannot find Kubernetes canonical name from friendly name [authority]`,
breaking the form entirely.

This change removes all references to authorities in the form,
restoring functionality.

This was validated against a edge-25.3.3 linkerd/linkerd-viz install by
performing a successful tap with the new code in the web UI.

Fixes #13841
