fix: quote dateFormat and gate hidden credential field focus

Quote the comma-bearing dateFormat default; QSettings reads an
unquoted comma as a QStringList and SDDM's stringValue() then returns
the empty string, leaving the value inert. Note the caveat in the
README Panel section.

Set activeFocusOnTab per credential stage so Tab cannot reach the
offscreen, transparent field and silently append to the submitted
value. forceActiveFocus() ignores activeFocusOnTab, so focusStage()
still lands focus in each stage.

Apply the remaining review fixes: compare the PowerBar fallback as a
string, animate the back chevron width, give both opacity behaviours
an OutCubic easing, gate the clock timer on panel visibility, clamp
panelWidth to 1, and reword stale "card" prose to "panel".
