ambient-runner Dockerfile requires non-standard build context

Problem

The ambient-runner Dockerfile uses COPY ambient-runner /app/ambient-runner, which assumes the build context is components/runners/ — one level above the Dockerfile's directory. This is unlike every other component, where the build context matches the Dockerfile's parent directory:

Component	Dockerfile	Context	COPY pattern
backend	components/backend/Dockerfile	components/backend/	COPY . .
frontend	components/frontend/Dockerfile	components/frontend/	COPY . .
operator	components/operator/Dockerfile	components/operator/	COPY . .
public-api	components/public-api/Dockerfile	components/public-api/	COPY . .
state-sync	components/runners/state-sync/Dockerfile	components/runners/state-sync/	COPY *.sh ...
ambient-runner	components/runners/ambient-runner/Dockerfile	components/runners/	COPY ambient-runner ...

The GitHub Actions workflow in prod-release-deploy.yaml handles this by explicitly setting context to ./components/runners, but build systems that derive context from the Dockerfile location (e.g. Konflux) fail with:

COPY ambient-runner /app/ambient-runner
Error: copier: stat: "/ambient-runner": no such file or directory

Proposed fix

Change the Dockerfile's COPY to use . (current directory) instead of the subdirectory name:

-COPY ambient-runner /app/ambient-runner
+COPY . /app/ambient-runner

Then update the GitHub Actions workflow context to match:

-{"name":"ambient-runner","context":"./components/runners","image":"...","dockerfile":"./components/runners/ambient-runner/Dockerfile"},
+{"name":"ambient-runner","context":"./components/runners/ambient-runner","image":"...","dockerfile":"./components/runners/ambient-runner/Dockerfile"},

This makes the runner consistent with every other component and removes the special-case context override.
