Improve dashboard empty states for first-time users

[asamassekou10]

Summary

Improve dashboard empty states for first-time users who have no scans, no findings, or no connected repositories yet.

Why This Matters

New users decide quickly whether a product feels understandable. Empty states should make the next action obvious and reduce confusion.

Suggested Starting Point

• webapp/app/app/
• webapp/components/
• /app/guide for copy and screenshots

UX Goals

• "No scans yet" should point to starting a scan and reading the guide
• "No findings" should celebrate clean scans and suggest CI/PR Guardian setup
• "No repos" should explain local scans vs connected GitHub repos

Acceptance Criteria

• Adds clear empty states with one primary action each
• Uses existing premium dashboard visual style
• Links to /app/guide where helpful
• Works on mobile and desktop
• npx tsc --noEmit passes in webapp

Hi! I would like to work on this issue. Please assign me to this issue if that's ok. Thanks. :)

[asamassekou10]

Thanks @AlvyRahman, assigned! Appreciate you picking this up.

A good starting path for this one:

• Look through the current dashboard pages under webapp/app/app/
• Reuse the existing premium dashboard styling instead of introducing a new visual system
• Focus on three states: no scans yet, no findings, and no connected repos/projects
• Link to /app/guide where it helps a new user understand the next step

For verification, please run:

cd webapp
npx tsc --noEmit

Feel free to open a draft PR early if you want design feedback before polishing everything.

Thanks for assigning this to me, @asamassekou10 ! I will start working on it as early as possible and will submit a draft PR as soon as it's ready.

Confirmed reproducible on Node 20 + macOS. Interestingly it doesn't happen if you set NODE_OPTIONS=--max-old-space-size=512.

Hi @AlvyRahman, quick check-in. Hope you’re doing well.

Are you still interested in working on this issue? No pressure at all if things got busy.

Hi @asamassekou10, Thanks for checking in, and yes, I'm still very much interested in working on this.

However, I haven't been able to start working on it yet due to business in my day job along with a few other personal work. Apologies for the delay.

Let me know if this is a critical/time-sensitive issue — if so, I'll make it a priority and try to start as soon as possible.
