fix(status): AMSAT page load failure, refresh spinner, retry button

- P0: fetchStatus() now runs on Dispatchers.IO - the previous
  synchronous URLConnection on the main thread threw
  NetworkOnMainThreadException and showed "load failed" on every open
- P1: refresh button rotates a vector icon (ic_refresh) instead of the
  "↻" text glyph, whose off-center font metrics made the spinner
  orbit around a shifted pivot
- P2: error state gains a Retry button (4 locales); amsat_refresh
  string added (5 locales)
- versionCode 456 (bump for reinstalling over 455), versionName stays 4.5.5
