fix: stabilize user-profile save and hydration flow

[Rustix69]

• Fixes : [BUG] User Profile save throws WebSocket CLOSED errors and profile fields load blank initially #317

Summary

• Fixes websocket publish race in NostrManager by awaiting relay reconnects before publish/subscribe.
• Fixes blank/late rendering on /settings/user-profile by tying loading UI to ProfileMapContext hydration state instead of a premature local loading flag.
• Starts an early fetch for the signed-in user profile in app bootstrap (pages/_app.tsx) so profile data is available sooner.

Problem

Editing and saving profile details on /settings/user-profile could trigger:

• WebSocket is already in CLOSING or CLOSED state errors during publish.
• Temporary blank profile form fields until later fetch/cache hydration.

Root cause

• Relay reconnect was initiated but not awaited before publish/subscribe.
• User-profile page cleared local loading too early, before global profile context was hydrated.
• Current-user profile fetch happened late in initialization sequence.

Changes

• utils/nostr/nostr-manager.ts
  • Made keepAlive async.
  • Await reconnect completion in both subscribe and publish.
• pages/settings/user-profile.tsx
  • Removed premature local fetching state behavior.
  • Derived loading state from profile context readiness + current user profile presence.
  • Hydrates form only after profile context is no longer loading.
• pages/_app.tsx
  • Added early current-user profile fetch during startup and awaited it before broader profile fetch completion.

Test plan

• Unit tests: npm test -- --runInBand utils/nostr/__tests__/nostr-manager.test.ts
• Manually open /settings/user-profile and verify fields do not render blank before hydration.
• Edit profile fields and click Save Profile; confirm no CLOSED/CLOSING websocket errors.
• Reload/revisit /settings/user-profile and verify saved values appear promptly.
