chore(ci): remove legacy prowler-api/ui/mcp cloud-deployment dispatch jobs

[cesararroba]

Context

The trigger-deployment jobs in the api/ui/mcp container-build-push workflows fired repository_dispatch events (api-prowler-deployment, ui-prowler-deployment, mcp-prowler-deployment) to kick off the legacy cloud deployment workflows. Those cloud deployment workflows targeted dev stacks that have since been decommissioned, so these dispatch senders no longer have a receiver.

These container-build workflows are synced upstream (prowler → prowler-cloud), so the senders must be removed here too — leaving them in OSS prowler would re-introduce them on the next sync. The companion cloud-side removal is prowler-cloud PR #4691.

Description

Removes the trailing trigger-deployment job from each of the three container-build-push workflows:

• .github/workflows/api-container-build-push.yml (api-prowler-deployment)
• .github/workflows/mcp-container-build-push.yml (mcp-prowler-deployment)
• .github/workflows/ui-container-build-push.yml (ui-prowler-deployment)

Each removed job was a leaf (needs: [setup, container-build-push]) with nothing depending on it, so no needs: rewiring was required. All other jobs (setup, notify-release-started, container-build-push, create-manifest, notify-release-completed) are untouched.

pr-merged.yml is intentionally left alone — it dispatches prowler-pull-request-merged (the PR-sync mechanism), not a deployment.

Steps to review

• Confirm only the trigger-deployment job block is removed in each of the 3 files.
• grep -rn 'trigger-deployment\|prowler-deployment' .github/workflows/ returns no matches.
• pr-merged.yml's prowler-pull-request-merged dispatch is still present.
• Each edited workflow still parses as valid YAML and retains its other jobs.

Checklist

• Review if backport is needed. (CI-only change, no backport needed)

📝 Walkthrough

Walkthrough

The trigger-deployment job is removed from all three container build-push workflows (api, mcp, ui). Each removed job previously used peter-evans/repository-dispatch to send a deployment event with the commit SHA and short SHA to a downstream dispatch repository after a successful push build.

Changes

Remove deployment dispatch from container build workflows

Layer / File(s)	Summary
Remove trigger-deployment job from all three workflows .github/workflows/api-container-build-push.yml, .github/workflows/mcp-container-build-push.yml, .github/workflows/ui-container-build-push.yml	Deletes the trigger-deployment job in each workflow, which conditionally fired on push events after a successful build and invoked peter-evans/repository-dispatch to emit api-prowler-deployment, mcp-prowler-deployment, and UI deployment events with sha/short_sha payloads to the CLOUD_DISPATCH repository.
