refactor(sdk): split hooks, dsr-portal, provider, sync approaching 500 LOC

All four files split into focused sibling modules so every file lands
comfortably under the 300-LOC soft target (hard cap 500):

  hooks.ts (474→43)  → hooks-core / hooks-dsgvo / hooks-compliance
                        hooks-rag-security / hooks-ui
  dsr-portal.ts (464→129) → dsr-portal-translations / dsr-portal-render
  provider.tsx (462→247)  → provider-effects / provider-callbacks
  sync.ts (435→299)       → sync-storage / sync-conflict

Zero behaviour changes. All public APIs remain importable from the
original paths (hooks.ts re-exports every hook, provider.tsx keeps all
named exports, sync.ts preserves StateSyncManager + factory).
