run ensure_flag_arg_type for short flag values (#14074)
Closes #13654

# User-Facing Changes

- Short flags are now fully type-checked,
  including null and record signatures for literal arguments:

```nushell
def test [-v: record<l: int>] {};
test -v null # error
test -v {l: ""} # error

def test2 [-v: int] {};
let v = ""
test2 -v $v # error
```

- `polars unpivot` `--index`/`--on` and `into value --columns`
now accept `list` values
