refactor: remove setinputdefaultvalue as obsolete from actions

[maxy-shpfy]

Description

Removes the redundant setInputDefaultValue action and replaces all usages with the existing setInputValue action, which serves the same purpose. This consolidates the two duplicate functions into a single action for setting an input's value.

Test Instructions

1. Open a pipeline in the Editor
2. Set a default value on a component input via the AI Chat tool bridge
3. Verify the value is correctly applied and that undo/redo behavior works as expected

Additional Comments

setInputDefaultValue and setInputValue were functionally equivalent. This change removes setInputDefaultValue entirely and updates the CSOM bridge and useIOActions hook to use setInputValue directly.
