Fix #134505: Bevel redo panel closes when defining profile

Caused by 1bde901bf2
`UI_BTYPE_CURVEPROFILE` button has undo flag set. see button-layout in:
`edbm_bevel_ui() -> uiTemplateCurveProfile()`.

This  forces an undo push with the help of `ui_apply_but_undo/ui_apply_but_funcs_after`.
To handle the situation, skip undo push for buttons in hud region.
