#14539 Add shared-axis, pinned-range indicators and Auto Zoom command for axis objects

Replace the chain/padlock icon with a simple two-headed-arrow icon
(SharedAxis.svg) for linked time/property axes.

Add a pinned-range project-tree tag shown when an axis range is
user-defined, using the standard gray pinned.svg icon. The tag
refreshes immediately regardless of the code path that changes the
range/auto-zoom state (Zoom All, data source changes, axis linking,
UI edits), and clicking the tag releases the user-defined range so
the axis auto-zooms again.

Add RicToggleAxisAutoZoomFeature, a checkable context-menu command
on Y-axis and time-axis objects that toggles auto-zoom and keeps the
pinned/user-defined-range tag in sync in both directions.

Move axis-specific context-menu entries out of RimContextCommandBuilder
into appendMenuItems() overrides on RimPlotAxisProperties and
RimSummaryTimeAxisProperties, per the project convention of keeping
object-specific menu logic in the object.

Fix RimSummaryPlot::timeAxisSettingsChanged() to actually re-apply
auto-scale to the plot widget when auto-zoom is re-enabled on the
time axis; previously only the property was updated, and no
recompute of the plotted range was triggered.
