chore(deps): upgrade motion to 13.x#106

motion 12.43.0 -> 13.1.1. no code changes needed.

sourced from motion.dev/docs/react-upgrade-guide and the upstream CHANGELOG, 13.x entries only:

• 13.0.0 — the only breaking change in the whole major: dropped the optional @emotion/is-prop-valid dep in favour of explicit <MotionConfig isValidProp={isPropValid}>. only bites emotion / styled-components users. we have neither, and no motion.create(StyledX) anywhere
• 13.0.0 also fixes hardware-accelerated SVG final style on animation complete, and AnimatePresence marking nodes safe to remove
• 13.1.0 — Reorder multidimensional, auto axis detection, RTL
• 13.1.1 — guards window access in non-browser runtimes, better AnimatePresence compat with React 19 strict mode

last two are straight wins for us on React 19 + Next SSR.

usage inventory, all still valid under v13:

• components/ui/animated-group.tsx, animated-background.tsx, progressive-carousel.tsx
• components/features/landing/faq.tsx, feature-section-with-hover-effects.tsx
• components/admin/blog/create-blog-dialog.tsx, edit-blog-dialog.tsx
• lib/animations.ts

checks: typecheck clean, 203/203 tests, build ok.

browser verification (static checks can't see animation regressions), dev server + isolated Chrome:

• desktop 1280x720 — /ro home scrolled in 6 steps, AnimatedGroup reveals, feature-section useInView reveal, carousel slat transition + pagination all correct. /ro/faq accordion open animations correct
• mobile iPhone 14, confirmed 392x849 — /en home scrolled in 10 steps, same reveals correct. /en/faq expanded AND collapsed, which confirms the AnimatePresence exit path still runs (the thing most likely to break silently on this major)
• zero motion-related console errors; only pre-existing Clerk/Cookiebot/analytics noise

two gaps worth a look:

• components/ui/animated-background.tsx uses layoutId shared-layout but is imported by nothing, so it got no runtime coverage
• the two admin blog dialogs (AnimatePresence mode="wait") are behind Clerk auth and weren't visually checked. mode="wait" had no v13 changes, but that's the honest gap
