## Problem
- Local apps are hard to distinguish from hosted apps in browser tabs.
## Solution
- Add blue blueprint icons to local development in all 8 apps and Studio
CLI.
- Keep normal branding for production, hosted staging and self-hosted
Studio.
- Builds on #51419.

## Review instructions
- Start an app locally. Its browser tab should show the blue icon.
- Check Studio CLI uses blue and hosted staging uses white.
- Check production icons are unchanged, including Learn's black and
white icon.
- Run `node scripts/validate-favicons.mjs`. All 16 sets should pass.
Asset and routing checks, formatting and Common/Studio type checks
passed. Full builds have not been run.
