Overhaul wiki into step-by-step guides with MS Learn best practices (#81) Rewrite each workflow as a guided walkthrough (prerequisites -> numbered steps -> verify -> troubleshooting) and link out to Microsoft Learn where the extension wraps a Microsoft concept: - New 'Connecting & Authentication' guide: interactive sign-in + service principal, secret storage, Switch/Refresh Environment (0.5.x auth), and auth troubleshooting. (The old docs only covered service principal and the now-renamed 'Update Connection String'.) - New 'Portals / Power Pages' guide (pac pages connect/download). - New central 'Troubleshooting' page + cross-platform expectations. - Getting Started, Solutions, Web Resources, Plugins rewritten as step-by-step guides with MS Learn links (ALM/solutions, web resources, plugin best practices + debugging). - Fix stale details: webpack output is <prefix>_library.js (not prefix_bundle.js); Generate Typings must run before the first build (it emits dg.xrmquery.web.min); document Windows-only typings clearly. - Sidebar + Home updated for the new pages.
