feat: clinic→wallet record-update push

A clinician can push an updated record to a wallet-linked patient (permanent
share). The snapshot is signed with the clinic Ed25519 key and sealed to the
wallet's X25519 key — derived from its Ed25519 wallet number via the birational
map, verified byte-for-byte against the wallet's own derivation. Stored pending,
delivered over the /wallet relay live and on the wallet's next authenticated
connect (offline catch-up). The patient approves/denies in-app; the wallet signs
its decision, the backend verifies it, and the record is replaced only on
approval. Wallet pins the clinic key (TOFU) and warns on change.

Backend: walletRecordUpdates table + service, ed25519PubToX25519Hex helper,
POST /api/patients/wallet/push, GET .../link/:fileNumber|updates|updates/:id,
wallet:update-request / wallet:update-response relay events.
Frontend: "Push to wallet" dialog with live status, wallet-link gating on the
patient sheet, "Sent updates" list under Settings → Signing, walletPush /
walletUpdatesList locale namespaces across all five languages. Bumps to v0.5.0.
