Throw for empty or incomplete generateStaticParams results with output: export (#95969)
> [!TIP]
> This PR is best reviewed commit by commit.
### Why?
With `output: 'export'`, an empty array or incomplete params can be
reported as a missing `generateStaticParams` function, even when the
function exists.
### How?
- Throw when any `generateStaticParams` invocation returns `[]`.
- Throw when any composed parent and child params object omits a dynamic
route parameter.
- Extend the troubleshooting page added in #95968 with the
export-specific cases.
Stacked on #95968.
Supersedes #95388.
