Adds .d.ts declarations beside the untyped JS modules imported from
TS (api.js, navConfig.js, adminSchema.js, adminNav.js, src/data/*),
with shapes taken from the server routes and migrations. get/post/
patch/del now return unknown unless the caller names the response.
Fixes found along the way:
- website/email/instagram are bare strings from splitLinks, not Link
objects; OrganizationDetail's website and email pills rendered with
no href or label and now link correctly.
- The chapter map falls back to FALLBACK_COLOR for a region with no
colour instead of painting its tiles black.
Adds defineSection() so each page manifest entry's props are checked
against its own Component.
