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
