Adds a distinct, sync-gated "Delete everywhere" button to the conversation
delete dialog: it blocks the thread locally (instant + persistent, so it can't
flicker back mid-sync) AND broadcasts a self-addressed Control(del) via
sendChatControl so every other device — and a future restore from the seed —
hides it too. Carries the peer z-address as the control label so Restore can
match by address. The button is disabled until the wallet is fully synced
(lite uses its own sync-complete signal, since it never sets tip_known), with a
note explaining the on-chain signal + fee. The two local-only modes (Delete /
Delete & block) are unchanged.
New English strings fall back cleanly until translated (chat_delete_everywhere*,
chat_delete_needs_sync). Phase A, step 5 (delete UI). Restore dialog next.
