Add donation + service sections, GitHub funding button, Gitea repo public

- README: "Support this project" (GitHub Sponsors + Buy Me a Coffee, both verified live)
  and "Need this set up - or something built?" (setup service, custom development,
  maintenance) with the Hoelee Enterprise contact block
- .github/FUNDING.yml: github + buy_me_a_coffee, so GitHub renders the Sponsor button
- Gitea repo visibility flipped to public (API private:false; anonymous access verified 200)

+## Support this project
+
+Built and maintained on my own time, and given away under MIT. If it saved you
+money or hours, you can keep it alive:
+
+- **[Sponsor on GitHub](https://github.com/sponsors/hoelee)** — one-off or recurring, through GitHub Sponsors.
+- **[Buy me a coffee](https://buymeacoffee.com/hoelee)** — a one-off thank-you.
+
+There are no sponsors-only features and there never will be: everything stays in
+this repo, MIT. Starring it and reporting a bug are just as useful.
+
+## Need this set up — or something built?
+
+- **Setup service.** I deploy and configure carousell-monitor for you — NocoDB,
+  your Telegram bot, your search list, your filters — on your own server or NAS,
+  and hand it over working. Remote, fixed fee, quote on request.
+- **Custom development.** Hoelee Enterprise builds websites, web apps, internal
+  tools, scrapers/monitors, chat bots and API integrations. Python, PHP,
+  Java/Spring, Docker/Linux, and Web3 (Solidity/ethers.js).
+- **Ongoing maintenance.** Keep it running, upgrade NocoDB, add new search
+  sources or delivery channels.
+
+Tell me what you need and I will come back with a price and a timeline.
