minmax slider with configured step rounds values before setting them on change

[lubojr]

Bug Description

1. When using minmax format with step precision > 2 decimal places (e.g. step: 0.0005), values are rounded to 2 decimals on mount. This is an upstream issue to-be-resolved in fix: apply round attribute before setting initial pointer values mzusin/toolcool-range-slider#25 but until it gets merged (if), I will prepare a PR fixing this in jsonform.
2. Switching anyOf schema branches in eox-jsonform leaks values from previous branch instead of resetting to branch schema defaults when values exceed bounds.

Expected Behavior

• Slider keep precision based on schema step.
• Switching branches resets out-of-bound values to the new branch defaults.
