fix(desktop): align preview sidebar row styling (#6163)

## Summary

- apply the inactive primary-navigation opacity treatment to every
sidebar destination, including Pulse, Projects, and Workflows
- remove the duplicated Inbox and Agents conditionals so future gated
rows inherit the same hierarchy
- add E2E coverage for all inactive rows and restoration to full opacity
when selected

## Validation

- `pnpm --dir desktop build:e2e`
- `pnpm --dir desktop exec playwright test badge.spec.ts --grep "primary
navigation rows share the same inactive emphasis" --project=smoke`
- pre-push hook: desktop check, typecheck, and 4,984 unit tests
