refactor: reorganize GitHub workflows with consistent naming convention (#5891)

## Summary

This PR implements a systematic naming convention for all GitHub
workflows to improve organization and discoverability. All 22 workflows
have been renamed and grouped by logical categories with consistent
prefixes.

## Changes

### Naming Convention
- **`ci-*`**: Continuous Integration workflows (testing, linting,
validation)
- **`pr-*`**: PR-specific automation triggered by labels  
- **`release-*`**: Release management workflows
- **`types-*`**: TypeScript type generation workflows
- **`i18n-*`**: Internationalization workflows

### Key Renames
- `tests-ci.yaml` → `ci-tests-e2e.yaml`
- `vitest-tests.yaml` → `ci-tests-unit.yaml`
- `storybook-and-chromatic-ci.yaml` → `ci-tests-storybook.yaml`
- `auto-backport.yaml` → `pr-backport.yaml`
- `claude-pr-review.yml` → `pr-claude-review.yaml`
- `version-bump.yaml` → `release-version-bump.yaml`
- `publish-frontend-types.yaml` → `release-npm-types.yaml`
- `create-dev-pypi-package.yaml` → `release-pypi-dev.yaml`

### Test Workflow Improvements
- Grouped all test workflows under `ci-tests-*` pattern
- Fork-safe deployment workflows: `ci-tests-e2e-forks.yaml`,
`ci-tests-storybook-forks.yaml`
- Added comments explaining fork deployment security workarounds

### Documentation
- Added comprehensive `.github/workflows/README.md`
- Documents naming conventions, best practices, and workflow
organization
- Includes trigger patterns and external dependencies

## Benefits

1. **Better Organization**: Workflows are now grouped logically by
prefix
2. **Improved Discoverability**: Easy to find related workflows  
3. **Consistent Naming**: All workflows follow the same pattern
4. **Clear Purpose**: Workflow names immediately indicate their function
5. **Maintainable**: README provides guidelines for future workflows

## Test Plan

- [x] All workflow cross-references updated
- [x] Display names match new file names  
- [x] Fork deployment workflows properly reference main workflows
- [x] Release workflows reference correct npm types workflow
- [x] All workflows retain original functionality
