fix(wizard): accept integer examples in prompt placeholders

The previous extraction used `as_str()` only, which silently returned
None for numeric JSON examples. So a schema like
`"examples": [8080]` on an integer field — exactly the kind of example
that would benefit from a placeholder — produced no placeholder
despite the integer branch wiring one up. Widen the extraction to
also accept i64 and coerce to String, then pass through call sites
via `as_deref()`.

No schema in runtimedb today carries numeric examples, so this is a
pure consistency fix — but it aligns the code with what the original
commit's description claimed to support.
