fix(sdk): Fix circular dependency by removing redundant tsyringe setup import from PersistenceManager (#3367)

## Summary

Fix a circular dependency in the SDK by removing a redundant `import
'./setupTsyringe'` statement from `PersistenceManager.ts`.

The circular dependency chain was:
1. `PersistenceManager.ts` imports `setupTsyringe.ts`
2. `setupTsyringe.ts` imports `Resends.ts` (to register it with
tsyringe)
3. `Resends.ts` transitively depends on `PersistenceManager` through the
dependency injection graph

Since `setupTsyringe.ts` is already imported at the application entry
point (`StreamrClient.ts`), the import in `PersistenceManager.ts` was
redundant and only served to create this circular reference.

## Changes

- Remove unnecessary `import './setupTsyringe'` from
`packages/sdk/src/PersistenceManager.ts`
