Addresses Copilot review comments on PR #797:
- Containers panel title, initial focus selection, and the local-project
inclusion in getDiscoveredProjects all switched from
InDockerComposeProject to IsProjectScoped, so they stay consistent
when -p is given outside a compose dir.
- Adds TestIsProjectScoped table test covering all four combinations.
InDockerComposeProject is still used at the call sites that genuinely
require a compose dir (renderDockerComposeConfig, GetServices).
