docs(readme): promote sponsor section and add FUNDING.yml

Move the sponsor block from the footer to right after the author bio,
rewrite the copy to explain self-funded maintenance and token costs,
and split individual sponsorship from enterprise/custom work so the
paid-engagement path is discoverable. Add .github/FUNDING.yml so the
GitHub Sponsor button appears on issue/PR pages and links to PayPal.

+## Support This Project
+
+PPT Master is built and maintained by one person, fully self-funded. Every new template, bug fix, and documentation update runs through AI models that cost real money — and right now those token bills come out of my own pocket.
+
+If PPT Master has been helpful to you, consider chipping in. Sponsorship directly funds more templates, faster fixes, and keeps this project free and open-source.

+**Enterprise / Custom work**

+Need a custom industry template, private deployment, or integration consulting? I take on a limited number of paid engagements each quarter.
