We use different text for guest users, specifying that they can
only search in channels they can view.
The issue description suggests the same for spectators, but
we already use different text for them.
The search-operators help overlay is also updated with the same.
Fixes#30902
Since we more space now in info overlay after recent width increase
and 40 / 60 split between columns, we have the space to show the
poll header at its normal font size of `18px` without making it wrap
to the next line at even medium width.
Updates translated strings in web/ that do not need updates to any
tests. The majority of these strings are also unique to the file/
template that they are in. A few have overlap with one other file.
Some changes here update placeholders/variables in these strings to
no longer use stream so that all the translation updates for this
rename happen at the same time.
The exception to this are cases of "<z-stream>" placeholders in
these translated strings.
Part of the stream to channel rename project.
