feat(discover): rewrite filter UI to align with backend DiscoverController 5 params

- Top chips: 推荐(重置) / 丹阳本地(regionCode=321181) / 年龄 / 学历 / 婚姻
- Each chip has real active state bound to applied filter value
- Panel expanded to 4 sections: age slider + region + education + maritalStatus
- Param names fixed: minAge/maxAge/regionCode/educationCode/maritalStatus
- Data flow: panel temp -> onApplyFilter -> applied -> _buildParams -> API
- Panel opens with current applied values, closes with openFilterPanel/closeFilterPanel
