email: charset decoding, inline attachments, UI fixes

- respect charset from Content-Type when decoding body and headers
- detect inline attachments with filenames (not just disposition: attachment)
- fix broken decodeQuotedPrintable reference in parseAttachments
- white background for email iframe (emails designed for light bg)
- sticky header in email list, scrollable message area
- arrow key navigation between emails with scroll-into-view
- /email/:id routing for deep linking to specific emails
- empty folder shows "No emails in this folder" instead of losing header
- fix attachment viewer header overlap with dialog close button
