Subject: [PATCH] feat: wire real signature verification in onboarding

OnboardingVerify.vue now signs a random challenge via node.signChallenge
and auto-verifies using identity.verify with the node's DID. Shows
green checkmark on cryptographic verification success.

 - [x] **IDENT-02** — Update onboarding to show DID + npub. In `neode-ui/src/views/OnboardingDid.vue`, after fetching the node DID, also fetch `node.nostr-pubkey` (already exists as RPC endpoint). Display both: "Your DID: did:key:z..." and "Your Nostr ID: npub1..." with copy buttons for each. Add a brief explanation: DID for Web5/federation, npub for Nostr apps. Store `nostr_npub` in localStorage alongside `neode_did`. **Acceptance**: Fresh onboarding flow shows both DID and npub on the identity screen. Deploy and verify at http://192.168.1.228.
 
-- [ ] **IDENT-03** — Wire real signature verification in onboarding. In `neode-ui/src/views/OnboardingVerify.vue`, replace `generateMockSignature()` with a real call to `rpcClient.signChallenge(challenge)`. Generate a random challenge string, send it to the backend, display the real Ed25519 signature. Add a "Verify" button that calls `identity.verify` with the DID, challenge, and signature to prove the node controls its keys. Show green checkmark on success. **Acceptance**: Onboarding verify step shows real cryptographic signature and verification succeeds. Deploy and verify.

 - [ ] **IDENT-04** — Wire real encrypted backup in onboarding. In `neode-ui/src/views/OnboardingBackup.vue`, replace the mock JSON display with a real call to `rpcClient.createBackup(passphrase)`. Add a passphrase input field (with confirmation). Call `backup.create` RPC, then offer the encrypted backup blob as a downloadable file. Show the backup metadata (DID, timestamp, encrypted: true). **Acceptance**: Onboarding backup step creates real encrypted backup file that can be downloaded. Deploy and verify.
