- Schema v33: add error_stack_trace and is_permanent columns to sync_logs
- SyncLogEntry gains stackTrace and isPermanent fields; SyncLogRepository.log()
gains matching optional parameters; IMAP and JMAP sync loops forward the
stack trace string and isPermanent flag when writing error entries
- New lib/ui/utils/about_markdown.dart utility shared by AboutScreen and the
sync log copy feature; builds the markdown table including Android device
info (manufacturer, model, OS version) via device_info_plus
- AboutScreen uses the utility and adds Android device info row
- SyncLogScreen: subtitle shows "Error (permanent)" for permanent errors;
expanded view shows stack trace in red monospace; each tile has a Copy
button that copies a markdown summary of the entry plus the About section
- Migration test updated for v33; new repo test for stackTrace/isPermanent
