feat(splash): random silly loading GIF (wow-lite-wallet tradition)

The wallet-open splash now shows a random loader from a bundled set (13
curated GIFs from wownero/wow-lite-wallet, ~2.2MB) instead of the static
key icon — auto-discovered from :/silly, aspect-scaled to 56px, falls back
to the key pixmap if none present. Assets by a friend (same Wownero family).
