- Add _decode_mime_filename() helper with Q-encoding fallback decoder
- Use helper for both new and existing email attachment saving
- Handles edge cases where email.header.decode_header fails on partially processed filenames
- Decode =?utf-8?q?...?= filenames before sanitizing for both new and existing emails
- Prevents filenames like __utf-8_q_Wire_236095209372_2Epdf_2Ehtml__
- Uses email.header.decode_header + make_header for proper decoding
- IMAP sync now saves attachments for existing emails that have has_attachments=true
but no attachment records in the database (retroactive attachment saving)
- Replace silent exception catching with logger.warning for attachment save failures
- Add logging module import and logger instance
- This fixes the issue where 62 emails had has_attachments=true but 0 attachment records
- Fix sync error: backend returns {synced, error?} not {success, synced_count}; frontend now checks error field
- Decode MIME encoded-words (=?UTF-8?Q?...?=) in backend during IMAP sync for subject/from/to/cc headers
- Add frontend decodeMimeHeader() utility for already-stored encoded subjects (MailList + MailDetail)
- Make pagination sticky at bottom of mail list (flex-col h-full, ul scrolls, pagination flex-shrink-0)
- Make pagination compact: smaller padding (px-1.5 py-0.5), text-xs, smaller icons, tighter spacing
- Fix FlagUpdatePayload field names to match backend schema (is_seen/is_flagged)
- Replace dangerouslySetInnerHTML with sandboxed iframe (srcDoc, sandbox="")
- Add bulk mark read/unread with checkbox selection in MailList
- Add floating bulk action bar in Mail.tsx
- Add imap_sync_mail_flags() to push Seen/Flagged flags to IMAP server
- Call IMAP flag sync in PATCH /flags endpoint
- Add i18n keys for bulk actions (de/en)
