fix(M13): hydration mismatch on backlog list filter chips (#19)
useState initializers read localStorage synchronously, which produced
a different render on client (with persisted filterStatus='blocked')
than on server (which has no localStorage and rendered 'all'). The
chip-buttons that surface active filters caused a structural DOM
mismatch next to the Popover trigger, raising a hydration error.

Move the localStorage read into a post-mount useEffect, defaulting
state to the SSR-compatible 'all'/'priority' on first render. Add a
prefsLoaded flag so persist effects skip the initial render and
don't overwrite saved values with defaults.
