fix: Update Crowdin configuration to prevent directory prefixing

Problem:
- PR #45 created translations in wrong structure: {lang}/Resources/Private/Language/
- Should be: Resources/Private/Language/{lang}.{filename}.xlf

Root cause:
- Missing preserve_hierarchy directive caused Crowdin to prepend language codes
  as base directories
- Relative paths instead of absolute paths
- Not using proper placeholders for dynamic file handling

Changes:
- Added preserve_hierarchy: 1 to prevent language directory prefixing
- Updated to wildcard pattern with absolute paths (/Resources/...)
- Implemented %original_path% and %original_file_name% placeholders
- Added ignore directive to exclude existing translations from re-translation

This ensures future Crowdin syncs create translations at:
  Resources/Private/Language/{lang}.{filename}.xlf ✓
Not at:
  {lang}/Resources/Private/Language/{lang}.{filename}.xlf ✗

Note: Filename remains crowdin.yml (Crowdin default) - .crowdin.yml would
require additional configuration in Crowdin project settings.
