fix(i18n): deduplicate category labels by reusing providerForm keys

- Change ProviderForm to use providerForm.category* instead of providerPreset.category*
- Remove duplicate category keys from providerPreset namespace in both zh.json and en.json
- Fix naming inconsistency: use categoryAggregation (not categoryAggregator)
- Fixes issue where English UI would show Chinese defaultValue fallbacks

This ensures single source of truth for category labels and improves maintainability.
