[fix](trx-frontend-http): give satellite passes their own page

Pass predictions were a third view inside the Weather Satellite Decoder card, under Digital modes — a planning tool filed behind a decoder toggle, beside the FT8 and WEFAX panels it has nothing to do with. Nothing about knowing when a bird comes over belongs there. Move them to /satellites, reached from Tools alongside Statistics, Recorder, Settings and About: occasional destinations that live behind that menu rather than taking a slot in the operating strip. Adding a sixth strip button wrapped the phone nav onto two rows and cost the desktop strip its labels at 1280px, so the tab is hidden from the strip exactly the way its four peers already are — the nav is byte-for-byte what it was. The prediction code moves out of sat.ts into its own plugin that loads with the page, so the decoder card no longer carries it. Countdowns stop when the page is hidden and each visit reloads, since passes go stale while it is closed. The server grows a /satellites index route so a deep link or a refresh serves the SPA shell rather than a 404.
