Docs polish: active-pill sync, license-sidebar bug fix, pricing standardized, ~70 em-dashes removed

- docs.js (new): sync sidebar .active pill with location.hash on load, click, and hashchange so in-page anchor links (Architecture, Discount codes, Backups, etc.) update the pill instead of leaving it stuck on whatever was statically marked
- Wire docs.js into every page just before </body>
- license.html: sidebar Project/Operate order matches every other page (Project first)
- pricing.html: rewritten to use the standard docs layout (full sidebar groups, prose main, breadcrumb) instead of a one-off shell that felt detached from the rest of the docs
- Reference section: remove Admin API + SDKs anchor links (they masqueraded as separate pages but just scrolled within integrate.html); Wire format stands alone
- Pricing copy: Zaprite reframed as "expanded payment options including card payment capabilities", "shipping in v0.3" removed (it shipped), Patron rephrased as perpetual (never expires or renews)
- "Toggling inactive" cap-evasion language replaced — admin UI exposes delete only, no soft-disable affordance for products
- ~70 em-dashes removed across 8 pages using a small pattern set (elaboration→period, list-intro→colon, tight clarification→comma, parentheticals→parens). Decorative stamp ornaments and references to actual third-party UI labels are kept verbatim.
