* adding exports to backend package, page icons update
* Integrity report PDF generation
* Fixed inline attachment images not displaying in the email preview by modifying `EmailPreview.svelte`.
The email HTML references embedded images via `cid:` URIs (e.g., `src="cid:ii_19c6d5f8d5eee7bd6d91"`), but the component never resolved those `cid:` references to actual image data, even though `postal-mime` already parses inline attachments with their `contentId` and binary `content`.
The `emailHtml` derived value now calls `resolveContentIdReferences()` before rendering, so inline/embedded images display correctly in the iframe preview.
* feat: strip non-inline attachments from EML before storage
Add nodemailer dependency and emlUtils helper to remove non-inline
attachments from .eml buffers during ingestion. This avoids
double-storing attachment data since attachments are already stored
separately.
* upload error handing for file based ingestion
* Use Postgres for sync session management
* Google workspace / MS 365 duplicate check, avoid extra API call when previous ingestion fails
* OpenAPI specs for API docs
* code formatting
* ran duplicate check for IMAP import, optimize message listing
* Version update
