refactor: common vitest configurations (#1107)
## Centralize and Standardize Vitest Configurations ### What Changed * New centralized configuration system: Created testing/test-setup-config package with a factory-based approach for generating Vitest configurations * Setup presets: Introduced modular setup file presets that can be composed for different test types (unit, integration, e2e) * Simplified configuration files: Refactored 6 existing Vitest config files to use the new centralized system, reducing them from verbose configurations to simple function calls ### Benefits * Eliminates duplication: Removes repetitive boilerplate across multiple vitest config files * Ensures consistency: Standardizes test configurations, coverage settings, and setup files across all packages * Improves maintainability: Changes to test configuration defaults now only need to be made in one place * Better developer experience: New configs are more readable and easier to customize with sensible defaults and preset combinations The new system provides `createUnitConfig`, `createIntConfig`, and `createE2eConfig` factory functions that automatically handle common configuration patterns while still allowing customization through override parameters. Relates to first part of #1065 --------- Co-authored-by: Szymon.Poltorak <[email protected]>
