Section 6a cited line numbers and two paths from before the monorepo
split (WP-67). A line number goes stale on the next edit; a symbol
survives it. Replace every L<n> citation in the section with the
named symbol, fix the two dead paths (environment.ts now lives under
libs/shared, proxy.conf.json is now one file per app), and point the
read walkthrough at mijn-registratie.section.ts, where the RD-03
split moved the dashboard's <app-async> block.
Mark RD-31 done and update its README row.
