Rendering play resets constraints on pos selection in useEvalStore

[AloisSeckar]

When play is selected, min/target/max pos items are correctly evaluated on background:

However, once "Score play" is hit, the store resets (probably?) and +/- buttons can get into invalid state

Remove can be clicked and there is no way to recover

We need to preserve useEvalStore min/target/max pos items state when rendering output.

To prevent introducing another regression, be careful not to preserve something that should reset on the other hand...

Secondary issue - when user first picks from pos select, number of rendered pos selects reverts to "target pos items"

[AloisSeckar]

both issues should be fixed now
