## Description When retrieving email attachments using the IMAP hook, filenames containing non-ASCII characters (e.g. Cyrillic) are returned in RFC 2047 encoded format instead of properly decoded Unicode strings. **Example:** - Raw: `=?UTF-8?B?0J/QtdGA0LXRh9C10L3RjCDRgtC+0YfQtdC6INC/0YDQvtC00LDQtl8yMDI2LTA0LTIxLnhsc3g=?=` - Expected: `Перечень точек продаж_2026-04-21.xlsx` ## Fix Adds `_decode_filename()` to `MailPart` class that uses `email.header.decode_header` to properly decode RFC 2047 encoded filenames. Applied in `has_matching_name()`, `has_equal_name()`, and `get_file()`. Plain ASCII filenames pass through unchanged. ## Related Issue Fixes #65871 -- This is an automated message from the Apache Git Service.
