fix(cliproxy): add kiro/ghcp provider mappings to discoverExistingAccounts

- Replace hardcoded typeToProvider with dynamic lookup from PROVIDER_TYPE_VALUES
- Add email extraction from filename as fallback for empty data.email
- Fixes issue where Kiro/GHCP accounts were skipped during discovery

Closes #242
