API: Cannot delete documents with slashes in 'document_id' (404 Not Found)

[j2h4u]

Describe the bug
I cannot delete a document if its document_id contains a forward slash (/), even though such documents can be created via retain and appear in listDocuments.

To Reproduce

1. Create a memory with a path-like ID:

   POST /v1/default/banks/test/memories
   {
     "content": "test",
     "document_id": "folder/file.md"
   }

2. Verify it exists via GET /v1/default/banks/test/documents (it returns id: "folder/file.md").
3. Try to delete it via DELETE /v1/default/banks/test/documents/{document_id}:
   • Raw: DELETE .../documents/folder/file.md -> 404 Not Found (Router mismatch)
   • Encoded: DELETE .../documents/folder%2Ffile.md -> 404 Not Found (Router mismatch)
   • Double Encoded: DELETE .../documents/folder%252Ffile.md -> 404 Document not found (App logic mismatch)

Expected behavior
The API should accept encoded slashes in the document_id path parameter and correctly resolve them to the stored ID, allowing deletion.

Context

• Hindsight Version: (Latest Docker image)
• Client: Custom CLI using generated TypeScript SDK.
• Impact: Forces clients to use ID encoding strategies (like Base64URL) to work around the API limitation for file-based synchronization, and prevents cleanup of existing legacy documents.
