New nav entry, route, page. Renders the four-level tree
(Company/Project/Store/PaymentPoint) via AdminPartnerHierarchyFacade on top
of the core built in the previous commit - TEST/LIVE toggle, suspend/activate,
disable behind a confirmation (terminal + cascading, per contract §2), and a
read-only credentials list stating plainly that only the public key is ever
held.
Reload-after-action rather than local patch on suspend/activate/disable:
disable cascades to descendants server-side, so a local patch would leave
children showing a status they no longer have.
Company id is a constant for now (DEFAULT_COMPANY_ID) - company creation is
out of band per contract §4.3, and there is no company-selector UI yet.
Verified: 139/139 unit tests, arch:check clean, production build succeeds.
