Background

Task #29 creates signed Nostr events (zap requests kind 9734, DMs kind 4) and logs them to timmy_nostr_events. When NOSTR_RELAY_URL is set, EngagementService POSTs DMs to the relay, but ZapService does not. Relay communication should be centralised and robust.

Acceptance Criteria

Extract a NostrRelayClient singleton (artifacts/api-server/src/lib/nostr-relay.ts) that wraps WebSocket or HTTP POST to NOSTR_RELAY_URL
Implements exponential back-off retry (3 attempts, max 10s)
ZapService.sendZap() calls nostrRelayClient.publish(event) after logging
EngagementService.sendDm() uses the same client
GET /api/identity/timmy response includes relayUrl (or null) so the frontend can display relay connectivity status
Relay URL validated at startup (reachable check, warn if not)
