refactor(core): report capability audit facts directly - #3815

Summary

The capability audit was using permission labels for things that are not permissions.

This removes that mapping and reports the actual facts instead: whether a skill declares tools and the real status of each scheduled task. It also renames executableScheduledTaskCount to activeScheduledTaskCount.

Fixes #3386

Verification

• All 657 core tests passed
• Lint and formatting passed
• Affected builds and type-checks passed
• UI dependency and ASF header checks passed
• I tried the full UI suite, but the local Node test runner hung in existing DOM tests after 178 passed. I am not counting that suite as passing
• I did not run the full repository test suite

AI use

• No generative tool made a substantive contribution
• Generative tooling made a substantive contribution

Tool(s) and scope:

Codex helped implement the refactor, add the regression test, update the Storybook fixture, and run the checks.

Checklist

• Tests cover the change and fail without it
• Lint, format, typecheck and the affected suites pass locally
