Remove ALL existing code related to stored sponsors

Since we're moving to an entirely offline and manifest-based SL check, we don't need any of the complex stuff we had before. We just need a SINGLE endpoint to sign the JWT manifest sent by the gh-sponsors extension (see devlooped/gh-sponsors#8). Everything else is unnecessary now.

The functionality is reduced but simplified significantly, with a massive improvement in PII/GDPR compliance. There is no longer any direct nor indirect telemetry tracked since the user must explicitly run a command and install an extension in their machine before getting a signed manifest.

We also no longer provide a webhook for the GH apps, which will be deprecated too.

Fixes #31
