[feat](trx-rs): add GetSatPasses protocol command for server-side TLE management

Browse Source 
TLE refresh now happens only on trx-server (once at startup, then every
24h). Client fetches satellite predictions from server via new
GetSatPasses fast-path command and caches them locally, refreshing
every 5 minutes. Removes spawn_tle_refresh_task from trx-client.
