Reports whether PORTAL_TRUST_PROXY still carries a bare proxy hop count.
Fastify 5.12.1 removed that form, so such a value now resolves to "trust
nothing", which quietly collapses every caller into a single rate-limit
bucket. Callers use this to warn the operator to name the proxy's address
instead of counting hops.
A sign is tolerated so a stray +1 is still recognised as the old form and
earns the specific upgrade advice rather than the generic rejection notice.
