Add VIP selection page and related data models

This commit introduces a new VIP selection page (`VipSelPage.kt`) that allows users to choose between Premium and Standard membership plans.

Key changes include:

*   **New VIP Selection UI:**
    *   `VipSelPage.kt`: Implements the UI for selecting VIP plans, displaying prices, and benefits.
    *   `SelfProfileAction.kt`: Updated to include a "Rave Premium" button alongside "Edit Profile".
*   **Data Models for Membership:**
    *   `MembershipModels.kt`: Defines data classes for membership configuration (`MembershipConfigData`, `ConfigData`, `Member`, `Benefit`, `Good`), price models (`VipPriceModel`), page data models (`VipPageDataModel`), and request bodies (`ValidateProductRequestBody`, `ValidateData`).
    *   `VipModelMapper`: Provides functions to transform backend data into UI-friendly models for price and benefit display.
*   **API Integration:**
    *   `RiderProAPI.kt`: Added new endpoints `getMembershipConfig` to fetch membership details and `validateAndroidProduct` for product validation.
*   **Navigation:**
    *   `Navi.kt`: Added `VipSelPage` to the navigation routes.
    *   `ProfileV3.kt`: The "Rave Premium" button in the self profile action now navigates to the `VipSelPage`.
*   **Theming:**
    *   `Colors.kt`: Added new color definitions for premium buttons, VIP benefit highlighting, and price card states (selected/unselected).
*   **Assets:**
    *   `ic_member.webp`: New icon for the "Rave Premium" button.
