Build 56: wait for the mixnet before dialing relays; no on-screen keyboard

Two fixes from live testing:

1) Stuck on "Connecting…": the nostr service dialed relays without waiting for
   the bundled Nym sidecar to be up. On a cold start a fast wallet-open beat the
   mixnet bootstrap, every relay failed, and nostr-sdk backed off — so the wallet
   sat on "Connecting…" long after the mixnet was ready. Now we wait for the
   sidecar SOCKS5 port before connecting (instant once it is warm). Verified:
   service start -> relay catch-up in ~5s; the flag (Build 55) reflects it within
   2s.

2) On-screen keyboard on desktop: upstream Grim pops its own virtual keyboard on
   desktop (no_soft_keyboard = is_android()), which looked wrong in the wallet
   flows and competed with physical typing (intermittent dropped/duplicated
   chars). Goblin now uses native input on every platform — Android IME via JNI,
   physical keyboard on desktop — by defaulting no_soft_keyboard to true. Verified
   on desktop: no on-screen keyboard, reliable typing.
