refactor: Overhaul UserDetailScreen and enhance user post feed

This commit introduces a significant redesign of the `UserDetailScreen`, transforming it from a simple card-based layout to a more modern and refined profile view. It also replaces the basic list of user posts with a full-featured `PostCardItem` feed.

**Key Changes:**

*   **feat(UserDetailScreen):**
    *   Redesigned the user profile section with a cleaner, borderless layout, moving from a `Card` to a `Column`-based design.
    *   Enhanced user info display to include email and location as decorative "pills."
    *   Replaced the previous list of post metadata with a full `PostCardItem`-based feed, showing complete post content directly on the user's profile.
    *   Added loading skeletons for the profile and post list, as well as an improved empty state for users with no posts.
    *   Added a "bottom indicator" to signify the end of the post list.

*   **refactor(ViewModel):**
    *   Modified `UserDetailViewModel` to fetch and construct full `PostCard` objects for the user's posts, instead of just `PostMetadata`.
    *   This involves fetching `PostBody` and `Category` details for each post to provide a rich feed experience.

*   **refactor(Shared Element Transition):**
    *   Introduced `sharedElementPrefix` to `PostCardItem` and `UserDetailScreen` to create unique transition keys for elements (like avatars and names) that appear in multiple screens (e.g., `talk_post_...`, `userdetail_post_...`).
    *   This ensures that shared element animations are correctly scoped and avoids conflicts when navigating between different feeds and detail screens.
    *   The shared element transition for user avatar and name now works correctly from any `PostCard` to the `UserDetailScreen`.

*   **feat(Repository):**
    *   Added `getPostBody(postId)` and `getCategory(categoryId)` methods to `UserRepository` to support fetching the detailed data required for constructing `PostCard` objects.
