Minor QoL: Less aggressive paste/save-prevention and clearing for the Value condition of leaderboards #1149
Description
When creating a leaderboard it will prevent you from pasting anything that does not fit the "Value" criteria and the leaderboard cannot be saved until the "Value" condition is good. This does make sense but I think the warning indicator does that job well enough, the current implementation imo just makes it more annoying to copy over conditions from cheevos (for example when copying over a speedrun cheevo to make a leaderboard out of it, or just individual conditions from similar leaderboards/cheevos).
Steps to reproduce:
- have a leaderboard with an empty "Value" condition
- pasting any conditions without any or with multiple "Measured" will fail (requiring you to paste it elsewhere to change it)
- adding conditions manually and removing the "Measured", then clicking to another condition will empty out the "Value" conditions
