ci(workflow): build all images on manual trigger instead of specific input

Refactor the image detection strategy in the build-images workflow.

- Remove the `image` input parameter from `workflow_dispatch`.
- Update detection logic to handle events differently:
  - On manual triggers (`workflow_dispatch`), the script now scans the `images/` directory and builds ALL valid images found.
  - On push events, the script retains the `git diff` logic to only build images that have explicitly changed.
