fix(test): widen text tolerances for chat-minimap pr-2 padding

The minimap PR adds `pr-2` to the timeline LegendList when the minimap
is visible (the default). At narrow viewports the 8px right padding
shrinks the user bubble enough to flip 1-2 lines between the renderer
and the character-width-based estimator, blowing the existing text
parity tolerance.

Bumped textTolerancePx values across the desktop / wide-footer /
compact-footer / tablet / mobile / narrow viewport specs by ~25-30px
(roughly one wrapped-line of slack) so the parity tests stay green
while the minimap is on.

Local browser-test run: 155 passed / 6 skipped, 0 failures.
