docs(wiki): correct what reading each page whole turned up (#2036)

The last pass reviewed diffs, so it never saw a new paragraph contradicting an
older one on the same page, or a long-standing claim nobody had checked.
Plugin authors were told ctx.config carries their per-user secrets and that
definePlugin takes a permissions key — neither is true, and both fail silently.
FORCE_HTTPS was said to need TRUST_PROXY, which it does not.

+New items inherit the view you add them in: adding an item while in **My list** makes it Personal, adding it in **Shared** puts it in the shared group pool. To share an item with specific people, add it first, then open its Sharing control and choose them.
 
 Only the item's owner (the person bringing it) can change its sharing. Someone you shared an item *with* just sees it on their **My list** with a **by {name}** badge and can tick it off — they don't manage who else it's shared with.
