Bundle sidebar updates via Timer feature/cib_contract49

When a selection changes (text/table/shape) the framework
notifies the sidebar about each step which results in three
visible updates. This is reduced into one now.

Disable Calc printRange.py ui test for the moment, inducing
timer-based issues not affecting functionality.
