feat: enhance build process and testing workflow

- Updated package.json scripts to include separate unit and integration tests before building.
- Added a new script `test-build-test` to run tests before and after the build process.
- Introduced a new local CI/CD script for streamlined local development and testing.
- Refactored PlayerTab component to normalize skills data structure and added tooltips for Space Marine and Power Armour abilities.
- Added named export for Tooltip in DeathwatchRoller for reuse in other components.
