fix: prevent title input remount on outline update in view modal (#331)

The loadPageDoc effect depended on the `resolvedView` object reference,
so every title edit that propagated through the outline produced a fresh
view object, re-fired the effect, and called setDoc(undefined) — which
unmounted the editor mid-keystroke and reset the title to the
server-side value on remount. Depend on a boolean derived from
resolvedView instead, so the effect only fires on the genuine
"metadata absent → present" transition.
