refactor(sdk): Clean-up tsyringe setup

[mondoreale]

Summary

Centralizes the tsyringe dependency injection setup by introducing a dedicated setupTsyringe.ts module that handles the reflect-metadata import. This eliminates the need for scattered import 'reflect-metadata' statements across source and test files, making the DI configuration more maintainable and ensuring consistent initialization.

Changes

• Created packages/sdk/src/setupTsyringe.ts to centralize the reflect-metadata import
• Updated core SDK entry points (StreamrClient.ts, Config.ts, ConfigTypes.ts, PersistenceManager.ts) to import the new setup module instead of reflect-metadata directly
• Added setupTsyringe.ts to Jest's setupFilesAfterEnv configuration for automatic test initialization
• Added setupTsyringe.ts import to karma-setup.js to fix the browser test build
• Removed redundant import 'reflect-metadata' statements from 60+ test files

Limitations and future improvements

• The setup module currently only imports reflect-metadata, but could be extended in the future to include other tsyringe configuration or polyfills if needed

Pull request overview

This PR refactors the tsyringe dependency injection setup by consolidating all reflect-metadata imports into a single setupTsyringe.ts file. This improves maintainability by centralizing the reflect-metadata import, which is required for tsyringe decorators to work properly.

Changes:

• Created a centralized setupTsyringe.ts file containing the reflect-metadata import
• Updated main source files and test setup files to import from the centralized setup file
• Removed direct reflect-metadata imports from all test files (50+ files)
