docs: add license page + per-page Permacomputer Preamble footer

- docs/_source/license.rst — new RTD page that literalincludes the
  repo's LICENSE file (single source of truth, no duplication)
- conf.py rst_epilog — appended to every RST source so every doc page
  carries the Permacomputer Preamble + AGPL-3.0-only notice + link to
  the full license
- index.rst — adds 'Project / License' section to the toctree

The LICENSE file already had the full Permacomputer Preamble + complete
GNU Affero GPL v3 text (matches the whitepaper version).
