The docs say SetLabel behaves like SetTooltip on Windows, but the Windows setLabel was an empty stub and show() only applied the tooltip when the icon was added, so a label set before Run never reached the icon either. Route the Windows setLabel through setTooltip, fall back to the label in show() when no tooltip is set, and store the label and tooltip on the SystemTray before dispatching to the platform impl so Label() reports the current value once the tray is running. Fixes wailsapp#6045

- Line 532: Update the SetLabel flow and show() so explicit tooltips
consistently take precedence over labels, including immediately after SetLabel
and after an Explorer restart. Add a regression test covering
SetTooltip("explicit") followed by SetLabel("label") and verify both display
paths preserve the explicit tooltip.
In `@v3/pkg/application/systemtray.go`:
- Line 120: Synchronize access to the persisted tray state fields used by
SetLabel, SetTooltip, Label, and Windows show(). Guard reads and writes with the
existing synchronization mechanism, or serialize all accesses through
InvokeSync, while preserving the current getter and display behavior.

SetTooltip("x") followed by SetLabel("y") showed "y" until Explorer
restarted, when show() put "x" back. Both paths now go through
SystemTray.tooltipOrLabel, so an explicit tooltip always wins and the
label is only the fallback.
SetLabel and SetTooltip also wrote label and tooltip on the caller
goroutine while Label() and the Windows show() read them. Guard the two
fields with a small RWMutex.

In `@v3/pkg/application/systemtray.go`:
- Around line 302-304: Update the Windows tooltip-clearing path in
SystemTray.SetTooltip to pass tooltipOrLabel() rather than the raw tooltip
value, preserving the label as fallback when the tooltip is empty. Add a
platform-facing test covering SetLabel("label") followed by SetTooltip("") and
verifying the native tooltip receives the label.
- Around line 122-124: Update SetLabel and SetTooltip to serialize or version
their platform-dispatched callbacks consistently with the textLock write order,
ensuring older queued callbacks cannot overwrite newer tray text while Label and
tooltipOrLabel return the latest values. Apply the ordering mechanism across the
platform handlers, including setLabel and setTooltip.

…leared
SetTooltip("") handed the empty string straight to the Windows setTooltip,
which wrote an empty SzTip, so SetLabel("label"); SetTooltip("") left the
hover text blank instead of showing the label.
setTooltip and setLabel now both apply SystemTray.tooltipOrLabel through
one updateTooltip. The value is read when the dispatched call runs rather
than captured at the call site, so the icon always ends up with the latest
stored text whatever order the calls land in.

On Windows
SetLabelis documented to do the same thing asSetTooltip, but the WindowssetLabelwas an empty stub andshow()only ever applied the tooltip, so a label set beforeRunnever reached the icon.SetLabelandSetTooltipalso stopped storing the value once the platform impl existed, soLabel()kept returning the pre-Runtext.setLabelnow goes throughsetTooltip,show()falls back to the label when no tooltip is set, and both values are stored before dispatching to the impl. The new test forLabel()fails on master and passes here. I haven't hovered a real tray icon with this build, but the tooltip path is the existingShell_NotifyIconcall.Fixes #6045
