Surface Pro 11 iptsd 3.1.0 v2 source contract (experimental)

Experimental source-bearing companion release for the Fedora Live integration.

• Carries the unchanged pinned IPTSD 3.1.0 payload and complete corresponding fallback sources from v1.
• Adds the exact OE-owned Fedora RPM template and current closed Surface Pro 11 integration profile.
• Keeps the stable iptsd-v1 component and archive root while advancing the trust-pinned outer release to v2.
• Does not extend the existing X1E v19 pen evidence to Fedora, installation, USB boot, X1P, or suspend/resume qualification.
