fix(ajustes): stop settings row titles from wrapping and cutting off

FilaAjuste's title Text had no maxLines/overflow, and neither did its
trailing current-value Text. An unbounded value (e.g. a real station
name in "Emisora preferida") let the trailing Row claim unbounded
width, squeezing the title down until it wrapped across several lines
that the row's fixed height then cut short.

Constrain the title to a single ellipsized line and cap the trailing
value's width the same way. FilaAjuste backs all 12 settings rows, so
every row is protected, not just the one that happened to expose it.
