refactor(dashboard): Command Center — page pass + polish (slices 8-9)

[OneStepAt4time]

Aegis version

Developed with: v${v}

What

Follow-up to the Command Center redesign (#4814, merged). Applies the design tokens + patterns to the remaining pages and adds the final polish slice.

Slices

• 8. Page pass + approval chrome — remaining pages (Login, Metrics, Cost, Analytics, Audit, Pipelines, Routines, Activity) + approval surfaces (ApprovalBanner, AcpApprovalModal, PermissionPromptSheet): purple→amber, frosted→solid navy tokens, borders→--color-border, numeric values→font-mono, status→getStatusStyle.
• 9. Polish — amber :focus-visible ring baseline, working-status dot calm amber pulse (prefers-reduced-motion guarded), dead token/class fragments removed, minor consistency fixes.

Verify

• `npx tsc --noEmit` clean.
• `npm run build` passes.
• 50/50 a11y-css + statusStyles tests pass.
• Resolved a cherry-pick conflict on `a11y-css.test.ts` (both Argus's test-fix in develop and this slice asserted the amber outline — merged).

Driven via aegis (Claude Code sessions reading `dashboard/DESIGN.md`), same loop as #4814.

The Problem

CI Failure: test (ubuntu-latest, 20) — dashboard E2E test failure:

FAIL src/__tests__/PipelinesPage.test.tsx > PipelinesPage > shows step count for each pipeline
TestingLibraryElementError: Unable to find an element with the text: /2 steps/.

Root Cause: The PR wraps {pipeline.stages.length} in a <span className="font-mono"> in PipelinesPage.tsx. This splits the text "2 steps" across two DOM elements. The test uses screen.getByText(/2 steps/) which expects text in a single element.

Fix Required

Update PipelinesPage.test.tsx line ~120 to use a custom text matcher, or revert the font-mono wrapper on the step count.

Other Notes

• Clean, focused refactor. +35/-36 across 16 files. Good scope discipline.
• Design token migration consistent with #4814.
• Focus ring and dead code removal look correct.

Please fix the test and re-push. I will re-review immediately.
