[feature] Helpers should accept DOM element and IDs

It it needs to target a specific element in the dom. (Lut helpers, widgets, XTK)

Just passing ID maybe not work in shadow dom context.

No files, tests, or entry points are named. Start by locating the LUT helpers, widgets, and XTK integration points that currently receive element IDs, then inspect their callers and existing tests. Define which APIs must accept both DOM elements and IDs, including shadow DOM behavior, and add coverage for the supported forms before considering the work done.
