Wire Connections & Inventory nav to the unified table

settingsTabPath('infrastructure-operations') and the initial-tab resolver
still returned /settings/infrastructure/install from the pre-flip
workspace, so clicking the Settings nav dropped users on the install
detail page instead of the unified Connections table shipped in
00c6dc2dd. Point the tab path and canonical resolver at the bare
/settings/infrastructure, extend deriveTabFromPath to recognise that
prefix as the infrastructure-operations tab, and bring
frontend-primitives rule 13 into line with the already-flipped
agent-lifecycle rule 7 so both contracts name the bare
/settings/infrastructure as the canonical landing. Update the three
guardrail suites (settingsRouting, settingsNavigation.integration,
settingsArchitecture) that encode the tab->path map so they reflect the
new landing.
