feat(doctor): deep-link findings to the page where they are actioned

Doctor findings used to be dead-end statements — 'approvals
waiting for review' left the operator to find the approvals inbox
on their own. Every finding with a dedicated surface is now one
tap away from it:

- summary tiles: modules -> store, approvals -> approvals inbox,
  audit chain -> audit log (chevron affordance, tooltip + semantics
  button; the services tile stays plain — no dedicated page)
- modules/approvals panel rows link the same way
- the event-log headline opens the audit page next to the
  existing verify button
- host-services empty state gains a 'view the configuration'
  button opening the in-Studio config viewer the hint refers to
- the update banner's release-notes URL is now an underlined,
  clickable link instead of dead text

Tiles and the panel are public callback-driven widgets so the
widget tests pump them without a live hub. New DE+EN link labels.
