fix(cliproxy): propagate port in unified config and UI preset handlers

Edge case fixes identified in codebase review:
- Unified config variant detection: add settingsPath and port fields
- Provider editor: use variant port in handleApplyPreset/handleCustomPresetApply
- preset-utils: add optional port parameter to applyDefaultPreset()
