Release 26.04.30

New ftp/sftp service based on paramiko, deprecation pysftp (abandoware). This new service is a drop-in replacement for the old pysftp service, which is now deprecated. Supports modern key formats. (#845,#849)

Allow shift+wheel vertical scroll on grids (#826,#851): holding shift while scrolling the wheel no longer freezes the grid viewport on Windows

TimeTextBox popup styling and time cell alignment fixes (#833)

Checkbox visibility toggle in _ask dialogs (#829, #831): ensure layout recalculation and consistent visibility handling with other widgets types.

Allow shift key on pasteOnGrid onkeydown (#826,#830): The onkeydown handler on pasteOnGrid grids only allowed metaKey and ctrlKey through, blocking all Shift-only key events. After the DOM/CSS restructuring in PR #671, the contenteditable node receives keyboard focus more readily, making the Shift-scroll block manifest during normal range-selection interactions.
