VimL dicts serialise boolean-like settings such as `auto_export = 1`
as the JSON number `1`, not `true`. serde's default `Option<bool>`
deserializer rejects that, causing `serde_json::from_value::<InitOptions>`
to return `Err` and `.ok()` to silently discard the entire wikis list.
The server then fell back to `wiki_root` and could not resolve per-wiki
links, marking every cross-wiki link as broken.
Add an `opt_bool_or_int` serde helper that accepts JSON bool, `null`,
or integers (0 = false, non-zero = true), and apply it to `auto_export`,
`html_filename_parameterization`, `listsyms_propagate`, and `auto_toc`
in `RawWiki`.
