v1.8.2 - Font Vote: other ranks, Top 3 split, custom pairings

Adds three requested Font Vote improvements: (1) each card shows how every other team member ranked that pairing, below the current person's own rank control; (2) the grid now splits into the top-3 ranked pairings and an Other Options section for everything ranked 4th or lower; (3) a + Custom Option button next to + Random Pairing opens a form to hand-pick heading/body fonts and name a pairing, using the same curated font pool. No new REST routes -- reuses the existing options endpoint.
