chore: sync upstream main

[tarik02]

What Changed

• Merged 28 upstream-only commits through pingdotgg/t3code@78f462c4e.
• Adopted project and settings breadcrumbs, themed confirmation dialogs, automatic mobile EAS release and fingerprint checks, usage corrections, and mobile rendering fixes.
• Preserved fork release versions, GitHub-hosted workflow runners, desktop context-menu settings, and fork-specific behavior across overlapping web, desktop, and contract code.

Why

Actualizes the fork to current upstream while keeping intentional fork behavior where the same CI and client code changed.

UI Changes

This includes upstream UI changes. Screenshots were not captured because browser verification was not requested.

Checklist

• This PR is small and focused
• I explained what changed and why
• I included before/after screenshots for any UI changes
• I included a video for animation/interaction changes

Made with Codex using GPT-5.
