Fix open_commands actions running after menu item render

[lukichov1]

Issue

open_commands, used to reset meta state on menu open, were running one tick after menu open, while items were already being rendered with old state

this caused cases where [meta] values were reset correctly, but placeholders and dynamic_amount could still render stale values on menu open

Fix

run open_commands before item rendering and execute open_commands actions immediately when already on main thread
