docs: split Self-Hosting-and-Demo into two pages, self-hosting first Self-hosting (real Tandem account) and demo mode (no Tandem account) are different audiences with different setup steps; bundling them into one page buried the self-host walkthrough under demo instructions. Splits into Self-Hosting.md (presented first) and Demo-Mode.md, each linking to the other, and rewrites the physical-iPhone reverse-proxy section to state only the PumpSync-specific facts plus links to well-maintained self-hosted options (Nginx Proxy Manager, Caddy, Traefik) rather than documenting reverse-proxy setup itself.

docs: rewrite self-host/demo walkthrough, fix broken quickstarts Self-Hosting-and-Demo.md is now a full step-by-step guide (demo connection steps, self-host via published image or source build, TLS requirement, troubleshooting) instead of a thin config summary. Every documented backend quickstart that failed at startup (Getting Started, Testing and Verification) now includes the signing-key generation step or the minimum env for a bare dotnet run — they previously shipped the rejected placeholder key. Architecture and Features-and-Modes updated for the timezone/basal-id/dataSourceMode wire changes; Backend-Operations corrected on image tagging. Includes the maintainer's pending PumpSync-Backend -> PumpSync.backend naming pass across these same pages. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
