readme + license: fix license badge + drop irrelevant Docs badge

LICENSE.md had an explanatory paragraph wedged between the copyright
line and the MIT body, which broke GitHub's licensee-based SPDX
detector -- the License badge rendered "not identifiable". Stripped
the paragraph so the file matches the canonical MIT template; the
"this only covers top-level scaffolding" explanation is already in
the README's License section and in CLAUDE.md.

Also dropped the docs.joypad.ai badge from the README header -- that
site documents the joypad-os firmware, not joypad-tester, so linking
to it from a tester's "Docs" badge would mislead.
