v0.52.13

Fixed

• ICS text fields (SUMMARY, DESCRIPTION, LOCATION) now have RFC 5545 escape sequences unescaped on import; characters like ,, ;, \n, and \ are now displayed correctly instead of shown as raw backslash sequences
• When pushing events to a CalDAV server, SUMMARY and DESCRIPTION values are now properly escaped per RFC 5545, preventing corrupted data on round-trip
• CalDAV calendar names now appear correctly in the event edit modal's sync target dropdown; the dropdown was reading calendar.url and calendar.display_name instead of the API response fields calendarUrl and calendarName, causing empty or undefined entries
