Commit cc948b022 fixed the Patrol preflight strings that gated keyless
onboarding; this sweeps the rest. Error messages, readiness checks, and
guidance copy that still pointed at the retired Assistant & Patrol
settings page now name the real surfaces: Pulse Intelligence settings
for the area as a whole, and the Provider & Models settings page for
provider-credential guidance, matching the phrasing cc948b022
established. Pinning tests updated in step, including three
ai_handlers_test.go assertions cc948b022 had already left stale.
