fix: InboundAttachment filename should be an Option<String>

[thomasmost]

this field is sometimes null when returned by the API, so it should be an Option

---

Summary by cubic

Make InboundAttachment fields nullable to match API responses and prevent deserialization errors. filename, content_disposition, and size are now Option types.

• Migration
  • Handle None for filename, content_disposition, and size (e.g., if let Some(..) or unwrap_or).
  • Update pattern matches and trait impls that assumed non-optional values.

^{Written for commit 24df728. Summary will update on new commits.}

Hello! Thanks for the report, apologies for taking a few days to respond. I'll talk to the resend team before merging as this might be a bug in their backend.

@thomasmost again sorry for the delay. This was an issue in the Node SDK (i.e. you were right that it could be null). Will be releasing a new version in a few minutes. Thanks for bringing it up!
