fix(faucet): add removed styles that are still in use

[barbaraperic]

Related Issues

There's a bug in #13056 that affected styling on the /funds and /datacap routes by removing styles that were still in use. 🫠

Proposed Changes

I've restored the original styling by:

• Creating a dedicated file for these styles
• Importing this file specifically in the affected /funds and /datacap components
• Planning a proper styling standardization in upcoming PRs to prevent similar issues
