fix(runtime-host): retain authenticated owner routes

[M4n5ter]

Summary

• persist authenticated direct-peer route and coordination-relay rotations in the existing Owner Runtime Host profile
• fence background updates by profile incarnation so a stale connection cannot modify a removed or recreated profile
• preserve credential, Root identity, access authority, and all unrelated profile metadata
• rehydrate the refreshed routes on Desktop restart instead of falling back to stale connection-code hints

Verification

• npm run build:test
• npm run typecheck
• npm run lint
• npm run format:check
• node --test packages/runtime-host/dist/__tests__/host-profile.test.js
• node --test apps/desktop/dist/main/__tests__/runtime-host-profile-service.test.js
