fix: toolbar buttons now reactively show active formatting state

Browse Source 
All isActive() and getAttributes() calls in the template were not
reading the tick prop, so Svelte 5 never re-evaluated them when the
editor state changed. Extracted isActive() and getAttrs() helpers
that consume tick to establish the reactive dependency.
