iOS splash: quality-branded, crop-safe navy launch screen

The iOS splash read as unbranded for two concrete reasons:
1. The light-mode master (resources/splash.png) was on a WHITE background
   while the SplashScreen plugin paints #16294F navy -> a white->navy->app
   flash on light-mode devices.
2. The logo + "Biz Connect" wordmark spanned ~82% of the 2732 square, but the
   launch storyboard scales it scaleAspectFill; on tall iPhones ~27% of each
   side is cropped, clipping the wordmark edges.

New splash (both light + dark masters, identical navy so there is no flash):
brand navy gradient (#20396f -> #16294f) matching the plugin background, the
C-mark as hero, and the wordmark typeset in Corbel (closest installed match to
the brand geometric wordmark) sized to 1041px -> inside the ~1260px aspectFill
safe zone, so nothing clips on any device.

Also hardened codemagic.yaml: the asset step used `|| echo skipped`, which
silently shipped Capacitor's blank default splash if generation failed. Now it
hard-verifies the generated iOS Splash.imageset exists and fails the build
otherwise. Rides the next Codemagic build (native asset; no server redeploy).
