- Stream-encode file contents with new admin dash file-upload UI.
- Since we're not using multipart forms, there are hard limits on upload size - both on the server and browser. Warn for larger (> 5MB) files. The effective limit is around 10MB right now.
- Minor: validate SMTP host as part of config validation.
- Update Rust and JavaScript dependencies.
