Deploy from CI with Infisical and ship Payload changes as migrations

CI reads Infisical staging as the read-only convexmonorepo-ci machine identity, deploys the Convex functions, builds and pushes the image, and asks the VPS to redeploy. Payload schema changes now ship as migrations that production runs on startup; the baseline matches the production schema and is recorded as applied there. The local stack moves to its own ports and syncs the Convex runtime env, and the scripts pick up Infisical account switching, dev-kill and a cache-safe CI install.

+// INFISICAL_CLIENT_ID and INFISICAL_CLIENT_SECRET from the job's Gitea secrets,
+// and reads the project and host from .infisical.json. Plain Node, no CLI to
