PR Checklist

• I followed naming, styling, and TypeScript rules (see .cursor/rules)
• I performed a self-review (diff inspected, dead code removed)
• I titled the PR using Conventional Commits with a scope when possible (e.g. feat(service): add new Terraform service) - required for semantic-release
• I only kept necessary comments, written in English (watch for useless AI comments)
• I involved a designer to validate UI changes if I am not a designer
• I covered new business logic with tests (unit)
• I confirmed CI is green (Codecov red can be accepted)
• I reviewed and executed locally any AI-assisted code

Pull request overview

Ensures environments with zero services still show the expected actions in the environments list (instead of having an empty “Actions” cell), aligning the new navigation behavior with UI expectations.

Changes:

• Add a disabled “Manage Deployment” button (with tooltip) when an environment has no services / no deployment status.
• Always render the “Other actions” menu when the environment exists, defaulting state when deployment status is missing.
• Add a unit test covering the “no services” action rendering and tooltip behavior.
