phraser: the query answers as review rewrote them (V-521)

The owner's wording, taken from the PR 111 review, with one correction from the
PR 113 review folded in: {temp} {word} rather than {temp}°, because the degree
sign reads as nothing through piper.

What the wording changes: query_unknown drops "не знаю.", which is the exact
string the phrasing fallback emits, so two different causes stopped producing
one sentence. weather_nolocation stops reading voice.weather.default_location
out loud and just asks which city. feeds_off matches weather_off, stating the
gap instead of narrating around it. The passive doubles and the near-identical
pairs go.

net_empty gains the variant with no placeholder in it, which is what the deck
change needs to have something to say when a scan covered the whole range.

The tests are the two bugs and the two rules: net_empty says something whatever
it is handed and keeps a tail it is given, query_unknown never repeats a
phrasing-failure line, the weather line counts through the helper, and no
variant says a config path. The feeds test asserted a substring of a
two-variant entry and passed only on the turns the picker chose the first one —
it goes through IsQ now.
