Release v1.4.34 with DLC import package-name and 413 fixes

- Use DLC filename as package name in dcrypt fallback instead of
  inferring from individual URLs (fixes mangled package names)
- Add paste endpoint fallback when dcrypt upload returns 413
- Split decryptDlcViaDcrypt into tryDcryptUpload/tryDcryptPaste
- Add DCRYPT_PASTE_URL constant
- Expand container tests for 413 fallback and dual-failure scenarios
