docs(config): drop client-side keys and refresh per-wiki reference

Remove nested_syntaxes, maxhi and diary_start_week_day from the config
reference (block, tables and key lists) since the server no longer
consumes them, and note that language-tagged code fences are highlighted
automatically with no nested_syntaxes key.
