The faceted filter popover used a fixed width of 200px, which clipped
long option labels (e.g. user-defined channel group names) and forced
the truncated text to be unreadable without leaving a way to see the
full value.

- Switch PopoverContent from `w-[200px]` to
  `min-w-[200px] max-w-[360px]` so short option lists keep their
  current footprint while long labels can expand up to 360px before
  the existing truncate kicks in.
- Add `title={t(option.label)}` on the truncated label span so users
  can still hover to see the full text on extreme cases.

Closes #4905
