Stabilize profile image object URLs

[LiranCohen]

Summary

• cache profile avatar/hero object URLs by record identity so unchanged refetches reuse the same blob URL
• delay revoking replaced/missing image URLs so React Query background refetches do not break currently rendered <img> sources
• add profile query tests for unchanged refetches and delayed revocation

Why

After discovered-identity sync started invalidating profile queries correctly, React Query can refetch profile data while the UI is still rendering the previous result. The old fetchProfile() revoked previous object URLs at the start of every refetch, which made the browser try to load revoked blob: URLs and log net::ERR_FILE_NOT_FOUND even though the UI recovered quickly.

Tests

• bun run test -- src/enbox/queries/__tests__/identity-queries.test.ts src/enbox/__tests__/identity-sync.test.ts src/enbox/hooks/__tests__/use-identity-sync-reconciliation.test.tsx src/enbox/hooks/__tests__/use-sync-query-invalidation.test.tsx
• bunx tsc -b
• bun run test
• bun run lint (passes with existing Testing Library warnings)
• bun run build (passes with existing chunk-size warnings)

Closing this in favor of a clean branch based on current main. The replacement PR contains only the profile image object URL fix.
