[Feature Request]: Display dataset labels not names in Encoding and Filter panel

### Feature description

I'd like the label of a dataset rather than its name (e.g. "Adverse Events" rather than "ADAE") to be displayed in the encodings and filter panel. While there is a `label` parameter in the `cdisc_dataset()` function setting it does not have the desired effect. Right now I'm abusing the `name` parameter for this purpose (see example below) but this does not work for ADSL and also the name cannot contain spaces.

```r
cdisc_dataset(
"AdverseEvents",
adae,
keys = get_cdisc_keys("ADAE"),
code = paste(deparse(adae_code), collapse = "\n")
)
```
