test(D.2b): UiDatElement — cover DrawMode passthrough + media fallbacks

Browse source 
- Assert DrawMode values (not just File) in the existing named-vs-direct test
- Add ActiveMedia_NoMedia_ReturnsZero: empty StateMedia → (0,0)
- Add ActiveMedia_MissingNamedState_FallsBackToDirect: absent named key → DirectState
- OnDraw: replace `var (file, drawMode) = ...; _ = drawMode;` with idiomatic `var (file, _) = ...`
- Add `// exposed for unit testing` comment above ActiveMedia()
