refactor: reorganize Bruno API collection into subdirectories

- Move search-related requests into bruno/media-items/search/ subdirectory
- Rename Fuzzy Genre Filter.yml to Fuzzy Tags Filter.yml
- Keep scenario-based requests in bruno/media-items/scenarios/
- Improve collection organization and discoverability

This reorganization makes the Bruno API collection more organized by
grouping search endpoints together and updating genre filter to tags filter.

+  ## Field Values Search - Authors
+
+  Fetches distinct author values for autocomplete dropdowns with counts and similarity scores.
+
+  **Method:** GET
+
+  **Endpoint:** /api/media-items/search
+
+  **Authentication:** Required (Bearer token)
+
+  **Query Parameters:**
+  - `library_id` (string, required): Library UUID to search within
+  - `author` (string, required): Author name to search for (fuzzy match)
+  - `limit` (integer, optional): Maximum results to return (default: 50)
+
+  **How It Works:**
+  - Returns distinct author names from the library
+  - Fuzzy matches the search query against author names
+  - Includes count of books per author
+  - Includes similarity score (0-1, higher = better match)
+  - Sorted by similarity score, then by count
+
+  **Use Case:**
+  - Populate autocomplete dropdown when user types in author filter field
+  - Show user available authors with book counts
+  - Help users discover similar author names
+
+  **Response:** HTTP 200 (OK)
+  ```json
+  {
+    "results": [
+      {
+        "value": "Asimov, Isaac",
+        "count": 47,
+        "score": 0.8
+      },
+      {
+        "value": "Asimov, Isaac & Robert Silverberg",
+        "count": 2,
+        "score": 0.75
+      }
+    ],
+    "total": 2
+  }
+  ```
+
+  **Examples:**
+  - `author=asimov` → Returns "Asimov, Isaac" (47 books), "Asimov, Isaac & Robert Silverberg" (2 books)
+  - `author=rowling` → Returns "Rowling, J.K." (10 books)
+  - `author=tolkien` → Returns "Tolkien, J.R.R." (15 books)
+
+  **Frontend Integration:**
+  - Call this endpoint when user types ≥2 characters in author field
+  - Display results in `<datalist>` or custom dropdown
+  - Show: "Author Name (count)" format
+  - Allow user to select from suggestions
+
+  **Success Criteria:**
+  - Status: 200
+  - Returns array of author values with counts
+  - Results sorted by relevance (similarity score)
+  - Only returns authors matching the fuzzy search
