legal: font license texts on the ISO; permissive source-available MontaukOS license

- Ship each bundled font's license at 0:/os/licenses/: OFL-1.1 copies for
  JetBrains Mono, Noto Serif, and Roboto, and AGPLv3 + font-embedding
  exception for C059 (URW Base 35).
- THIRD-PARTY-NOTICES.txt gains sections for all four font families and
  now describes MontaukOS as source-available.
- license.txt rewritten as the MontaukOS Software License: use, study,
  modify, and redistribute freely with attribution; selling or bundling
  into commercial products still requires permission. Replaces the
  previous no-copy/no-modify/no-redistribute EULA.
- The MontaukOS license itself now also ships on the ISO
  (0:/os/licenses/LICENSE.txt, sourced from the website copy).
- man legal updated: license pointer + full third-party component list.
