Wrap the lines the merge resolution left long

`cargo fmt --check` failed the desktop job, on three files and for one reason:
routing the mask handlers through the `Masking` global was done by substituting
the call prefix, which is a text edit rather than a Rust one. It left
`window.global::<Masking>().on_part_join_picked(...)` on a line that had been
short enough as `window.on_mask_part_join_picked(...)` and no longer was.

Formatting only. The whitespace-stripped source is identical in the two `ui/`
files; the third differs by the trailing commas rustfmt adds when it breaks a
call across lines.

The matrix moves with it, because the tags shift by a few lines and the check
compares line numbers.
