fix(syntax): reject bare apis-container bodies and cross-mode duplicate api names

Bare bodies inside apis {} silently discarded their text with no error,
producing a do-nothing block. They now throw a ParseError naming the entry
and pointing at the response {} section. Duplicate-name detection for
dataApis moved from an incremental, order-dependent check (only saw prior
entries in the array) to a single post-parse pass over the whole ast.dataApis,
so it catches cross-mode duplicates (apis {} vs ssr { api }) regardless of
declaration order.
