feat: add sentinel dashboard roadmap and fix deployment/linting issues

- Deliver `docs/sentinel-dashboard-master-plan.md` and `docs/roadmap.md` with 2026-2035 roadmap and technical report plan.
- Fix Netlify `_headers` and `_redirects` formatting (2-space indentation, single trailing newline) and synchronize across root/public.
- Refactor `backend/server.js` and `backend/models/User.js` to strictly adhere to Standard JS style (no semicolons, single quotes, no trailing commas) and eliminate code duplication.
- Address Deno linting errors by prefixing unused variables and fixing CSP quote syntax.
- Add `deno.json` to correctly scope Deno checks and exclude unrelated project directories.
- Incorporate systemic risk thresholds (StaR-MoE Alignment/Entropy) into the governance dashboard plan.
