fix(frontend): Update UI code snippets to v0.96.0 unified invoke API

[mmabrouk]

Summary

• Updates all UI code snippets (registry, deployments, endpoints) to use the v96.0 unified invoke API
• Fetch config/variant snippets now use /preview/applications/revisions/retrieve instead of /variants/configs/fetch
• Invoke snippets now use /v0/invoke with structured data/references/selector format instead of /run with flat params
• Chat apps correctly include messages in data.inputs and show the Baggage header for session tracking

Files changed

• Fetch config snippets (curl, typescript) — new endpoint + key field for environment resolution
• Fetch variant snippets (curl, typescript) — new endpoint + application_variant_ref/application_revision_ref
• Invoke snippets (curl, python, typescript) — updated chat detection for new nested format
• createParams / createParamsFromSchema — build new data/references/selector structure
• VariantUseApiContent — variant invoke params use new format
• deploymentUrlAtomFamily — generates /v0/invoke instead of /run

Tested

• Verified all 4 scenarios against eu.cloud.agenta.ai production:
  • Fetch config by environment (new endpoint) ✅
  • Fetch config by variant (new endpoint, version as string) ✅
  • Invoke completion by environment (/v0/invoke) ✅
  • Invoke chat by environment + variant (/v0/invoke) ✅
• Lint passes clean

Test plan

• Open registry drawer for a completion app → verify fetch + invoke snippets show new format
• Open registry drawer for a chat app → verify messages in data.inputs and Baggage header
• Open deployments dashboard → verify environment-based snippets use new format
• Copy and run a generated snippet against a real app to confirm it works
