Stage 17 docs: round-4 UI (inline profile, double-tap/drag recall, hover-zoom, animated shuffle, lines-off board)

- UI_DESIGN: double-tap recall vs zoom, hover-hold drag auto-zoom, placing & recall
  rules, grid-lines toggle (gapless checkerboard default), animated shuffle; fix the
  stale MakeMove/Reset description (direct ✅ button + ↩️ Reset tab, no popover).
- FUNCTIONAL (+ru): optional trailing '.' in display names; profile edited inline.
- PLAN: robot early band [1,5]→[3,10] (#14); round-4 refinements + deferred #2/#16.
