Limit Selectors for Loop and Wait Nodes Are Buggy

Problem: Input fields for time limits in loop and wait nodes have poor UX - they reset to zero when clicked, don't allow proper editing, and don't clearly communicate maximum values.

Use Case: Users need to set specific time intervals for wait nodes and loop iterations but struggle with the current input interface that doesn't allow proper value entry or editing.

Proposed Solution: Allow users to type values directly, show clear error messages when limits are exceeded, and fix the input field behavior to allow proper editing without resetting to zero. 23:39-23:58
