feat: the shapes of the four hand-written .wikitool-*.json files live in one record each (config_shapes.py); loaders, doctor and docs/reference/configuration.md read them (#193)

The telemetry, remotes, upload and tasks loaders take field names, defaults, coercions and their Expected: text from the record and accept exactly what they did before. doctor WARNs on a telemetry file the policy silently reads differently. configuration.md carries one generated region per file, also checked in an instance. docs reference --apply now refreshes several regions in one page in sequence instead of keeping only the last.
