Subject: [PATCH] Release v1.4.35 with 413 handling for both dcrypt endpoints
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Handle 413 from paste endpoint (not just upload)
- Show clear German error "DLC-Datei zu groß für dcrypt.it" when both
  endpoints reject the file due to size
- Add tests for dual-413 and upload-413+paste-500 scenarios
