fix: resolve horizontal overflow on mobile control panel

[NearInfinity999]

Summary

Closes #64.
This PR fixes the horizontal overflow issue on mobile viewports for the top control panel. Added flex-wrap: wrap and justify-content: center to the .top-right container inside the mobile media query.

Why

On smaller screens, the control panel was strictly horizontal, pushing the rightmost buttons ("Sources", "What Signals Mean", etc.) off-screen and making them completely inaccessible to mobile users.

Scope

• Focused bug fix
• Small UX improvement
• New source
• Dashboard change
• Docs/config change

Validation

Tested locally using browser DevTools mobile device simulation. Verified that the buttons now stack neatly into grid rows on small screens without breaking the page width.

Screenshots

Config and Docs

• No new environment variables
• .env.example updated if needed
• README.md updated if behavior changed

Source Additions

N/A - CSS bug fix only.

Checklist

• This PR stays within one bugfix or one feature family
• I kept unrelated changes out of the diff
• I considered security for any mixed-source content rendering
• I tested the changed path locally
