Consume several per-wiki config keys that the server deserialized but
ignored, and remove keys whose effect is purely client-side:
- diagnostics: re-publish open-doc diagnostics on
didChangeConfiguration so a link_severity change takes effect
immediately; fix the single-key unwrap in apply_change so a minimal
`{ diagnostic: {...} }` payload isn't mistaken for a namespace wrapper.
- auto_toc: rebuild an existing TOC section on save (new
ops::toc_rebuild_edit, no-op when the page has no TOC).
- diary index: honour diary_header, diary_sort and diary_caption_level
when rendering the diary index body.
- links_space_char: apply on rename so spaces in the link target and
the on-disk path become the configured glyph (default " " = verbatim).
- list_margin: thread the per-wiki value into render_page_html.
- remove nested_syntaxes, maxhi and diary_start_week_day from the server
config: nested-syntax and heading highlighting are client-side, and
the weekly diary is ISO-week based so a custom week start has no clean
server-side meaning.
