List and Create Experiences

**GET:** List all experiences (drafts and published) for the logged-in user, ordered by last updated date. **POST:** Create a new experience with AI experience types and custom data. **Publishing Behavior:** - When an experience is fully published (all selected types succeed), the original draft is hidden from listings - When partially published (some types fail), the draft remains visible but only contains the failed types - Published experiences appear as separate entries with deployed resource UIDs **UID Format for Listing:** - **Draft experiences:** 'uid' contains the experience UID - **Published experiences:** 'uid' contains the deployed resource UID (domain/blog/quest), 'experience_uid' contains the original experience UID **Filtering and Search:** Supports extensive filtering by category, subcategory, draft status, etc. **Category, Subcategory and Tags Support:** You can specify category and subcategory using their names directly. Tags can be provided as a list of strings and will be created if they don't exist. The system will automatically resolve category/subcategory names to the corresponding objects. **Podcast Preset Selection:** For PODCAST experiences, include 'voice_type' in the data field with a valid preset code. First call GET /api/v1/podcasts/presets/ to list available presets (interview, panel, educational, narrative, debate), then use the preset code. The system validates that the selected preset has active voices available.
