fix: improve Coloris color picker visibility and button clickability

- Fix grid layout: add second column for input (grid-template-columns: var(--input-h) 1fr)
- Ensure color picker button is clickable with cursor pointer and pointer-events auto
- Set color picker z-index to 10000 to display above all UI elements
- Add global styles to ensure Coloris button is always clickable

Fixes issues where:
- Color picker appeared behind ElementPopup
- Button was not consistently clickable
- Grid layout was missing second column definition
