Add status footer badge

[Chris79OG]

Summary

• add a footer status badge that links to status.usewraith.xyz
• poll a configurable provider JSON endpoint every 60 seconds when VITE_STATUS_BADGE_JSON_URL is set
• document the monitor list, status env vars, and service-update process in docs/CONTRIBUTING.md

Notes

This handles the website/footer side of #12. The managed status provider setup, DNS CNAME, and live incident simulation still need repo-owner/provider access.

Verification

• pnpm build
• pnpm exec prettier --check src/components/Footer.tsx docs/CONTRIBUTING.md
• git diff --check

Repo-wide pnpm format:check currently fails on untouched existing files, so I verified formatting only for the changed files.

Closes #12

[vercel]

Someone is attempting to deploy a commit to the truthixify's projects Team on Vercel.

A member of the Team first needs to authorize it.

Local verification for this PR:

• pnpm build passed
• pnpm exec prettier --check src/components/Footer.tsx docs/CONTRIBUTING.md passed
• git diff --check passed

The current Vercel failure is the standard fork/team authorization gate. The code path builds locally; provider setup and DNS CNAME still require maintainer access.

Heads up — we've just set up a develop branch as the integration target for all Drips × Stellar Wave contributions, and I've retargeted this PR's base from main to develop on your behalf. The diff is unchanged; nothing to do on your end.

Going forward, please branch from and target develop. We'll periodically merge develop → main as we cut releases. Thanks for contributing!
