feat(docs): drift gate — docs frontmatter validated against real routes

Every API doc that declares frontmatter (method/path/auth/area) is now
checked by a unit test against three sources of truth:

1. Route registration: internal/router/*.go is parsed the way echo resolves
   it (group prefixes concatenate; scanner.go's parameterized groups seeded).
   Doc paths that no longer exist fail. (This is the check that would have
   caught the /api/api/admin/hash-conflicts split.)
2. Auth: frontmatter auth label must match the middleware chain
   (none|jwt|jwt+admin|device-token|optional-jwt).
3. Shapes: internal/docs/schema.go registry — example-request decoded with
   unknown fields DISALLOWED (typo guard), required-by-validate fields must
   appear (staleness guard), example-response top-level key set compared
   both directions against the marshaled handler type (or a RawMessage pin
   for hand-built map responses).

Five collections docs are the pilots with real handler shapes; notable
corrections they pin: update returns 201 (not 200), list excludes smart
collections unless include_auto=true, rule priority is 1-10 higher-wins
(docs claimed 1=highest), created_at is Go time.String() not RFC3339,
hide_finished/show_up_next toggles documented. CollectionResponse hoisted
out of GetCollections/GetBookCollections as CollectionSummary /
BookCollectionSummary so the registry can pin real types.

The gate fails on missing registry entries by design — that is the
maintenance contract. Known pre-existing (not this commit): vet copy-lock
warnings in media.go.
