fix(meta): show restriction alerts for inbox setup (#14974)

Instagram inbox creation and WhatsApp embedded signup on Chatwoot Cloud
now reflect the temporary Meta restriction. Instagram is hidden from
onboarding on Cloud, while the regular Instagram inbox creation page
shows a disabled action with a status-linked amber warning. WhatsApp
embedded signup on Cloud stays visible with its connect action disabled.
WhatsApp Call setup always uses the manual WhatsApp form.

Existing Instagram conversations and Instagram inbox settings on Cloud
also show amber warning banners with the public incident link.
Self-hosted installations keep their existing Instagram, WhatsApp, and
WhatsApp Call setup behavior because the temporary restriction is based
only on the Chatwoot Cloud environment check.
