Server module now declares `const api = { ... }` for apis {} blocks in
mode "any", dispatching in-process via requireRequestContext + the
existing __wrnexusCallApi transport helper. The try wraps only the
transport call; the response body runs after it, outside the try, so
a bug in the author's response code surfaces rather than being
mistaken for a request failure. A block with no error {} section
rethrows instead of resolving undefined.
Also closes the pageCtx.__wrnexusCallApi wiring gap in
dev-server/runtime.ts: it now forwards input through to
callApiFromContext instead of dropping it.
