test: Regenerate matplotlib 3.11 plot references to match CI timezone#8706

The matplotlib 3.11 accounting-plot references (added for the Python 3.14 DIRACOS build) were rendered in a UTC environment, but DIRAC's Graphs format time-axis labels in the machine's local timezone (GraphUtilities.add_time_to_title via time.localtime, and the *Graph classes via datetime.fromtimestamp). The DIRAC and DIRACOS2 integration CIs both render these plots in CET, so the UTC references were one hour off on the five time-axis plots and failed under matplotlib 3.11. Regenerate those five references from the matplotlib 3.11 CI output; the older <stem>.png references are unchanged.

The matplotlib 3.11 accounting-plot reference images added for the Python 3.14 DIRACOS build were rendered in a UTC environment. DIRAC's
Graphsformat time-axis labels in the machine's local timezone (GraphUtilities.add_time_to_titleviatime.localtime, and the*Graphclasses viadatetime.fromtimestamp) while labelling them "UTC", so the plots depend on the renderer's timezone.Both the DIRAC and DIRACOS2 integration CIs render these plots in CET, so the UTC references were one hour off on the five time-axis plots (
stackedline,cumulativeplot,timedstackedbarplot,qualityplot1,qualityplot2) and failed the comparison under matplotlib 3.11 in the DIRACOS2 (Python 3.14) build. The older<stem>.pngreferences were already CET, which is why DIRAC's own CI (matplotlib 3.10) kept passing.This regenerates those five references from the matplotlib 3.11 CI output so they match. No code change; the
<stem>.pngreferences are unchanged.Note: the underlying local-time-labelled-"UTC" behaviour in
Graphsis a pre-existing quirk, unrelated to this change.
