feat(export): wire ExportService — tray '내보내기...' menu + dialog

Tray now has 4th callback that opens directory chooser, exports all
notes via ExportService with includeMedia=true default. Dialog
message warns about raw_text plain-text + recommends private location.
Native toast on success/failure with note + media counts.
