Refactor "Trust model" page

[alexandratran]

Refactor the Trust and responsibilities page (now Trust model) to be more concise and less redundant, highlighting the trust assumptions in both deployment models, what participants can verify, who holds privileged contract roles, and the effect + recovery path for failures. Minor edits in related pages.

Note

Low Risk
Documentation-only renames and editorial restructuring with no runtime or contract behavior changes.

Overview
Renames the Trust and responsibilities doc to Trust model everywhere (sidebar, llms.txt, cross-links) and rewrites trust-model.mdx into shorter narrative sections: shared operator powers/limits, what participants can verify (public rollup vs private validium), trusted bridges, finalization-layer inheritance, System contract roles (replacing the old “Admin keys and upgrade authority” anchor #system-contract-roles), and Failures and recovery. Large comparison tables and duplicated per-model verification lists are removed in favor of pointers to Security and assurance and Deployment models.

Related doc tweaks: adds a System contracts glossary entry; clarifies that the finalization contract calls a verifier for zk-SNARK checks; trims redundant trust/DA copy on the validium page; updates key-management links to the new role anchor; small security/compliance/deployment copy and see-also cleanups.
