Sync packaging to live v1.84.0 deployment (CVE-2026-35029/59822 fix line)

- Dockerfile: pin ghcr.io/berriai/litellm:v1.84.0 (was floating
  main-v1.74.0-stable, which silently moved to a newer digest).
  v1.84.0 is the fix line for CVE-2026-35029 (auth bypass on
  /config/update, fixed 1.83.0) and CVE-2026-59822 (MCP session
  auth bypass, fixed 1.84.0, CISA KEV).
- Drop the v1.74.0-era sed CORS patch: upstream v1.84.0 moved the
  file and now reads LITELLM_CORS_ORIGINS natively.
- start.sh: export LITELLM_CORS_ORIGINS (the native v1.84.0 var)
  instead of LITELLM_CORS_ALLOWED_ORIGINS (the old sed-patch var
  that v1.84.0 ignores) — keeps CORS locked to chat.inference.coop.
- CloudronManifest: upstreamVersion 1.74.0 -> 1.84.0.

Live gateway already runs v1.84.0 (image digest
sha256:dc532d896ba8..., built 2026-10-02 04:50 UTC); this commit
makes the repo mirror the deployed packaging per the no-drift rule.
LITELLM_CORS_ORIGINS also set as a Cloudron env var on the app so
the running container honours it without a rebuild.
