revert(vtex): roll back to kubernetes-bun deploy (#429)

Reverts the Workers migration (#424–#427). The runtime cache fix from
decocms/studio#3299/#3300 didn't restore acceptable tools/list latency
(~5s/call still observed after 1.6.2). Going back to the working
kubernetes-bun pipeline; vtex stays on @decocms/runtime 1.3.1 with the
serve()-style entrypoint.

Restores: deploy.json entry, wrangler.toml deleted, deploy-vtex.yml
workflow deleted, server/main.ts back to bun serve(), package.json
back to deco-cli/openapi-ts deps, tsconfig/app.json restored.
