What Happened

The MEM+ and DAX buttons in the SpectrumOverlayMenu sidebar show their tooltip
briefly (~0.5 s) and then it disappears. MEM▶, the button immediately above,
works correctly.

All three buttons have tooltips set unconditionally in the constructor
(SpectrumOverlayMenu.cpp:148-158). No event filter intercepts QEvent::ToolTip
for these widgets. No setToolTipDuration override exists anywhere in the codebase.

Root Cause

SpectrumWidget has setMouseTracking(true) active at all times. Its
mouseMoveEvent calls QToolTip::hideText() unconditionally in the band plan bar
region (line 2470). Because SpectrumOverlayMenu is a child widget drawn over
SpectrumWidget, mouse-move events over the overlay buttons reach
SpectrumWidget::mouseMoveEvent, which tests the cursor y-position against
internal spectrum regions -- not against child widget bounds.

SpectrumOverlayMenu uses manual geometry (move()). Button positions within the
widget, and their corresponding y-coordinates inside SpectrumWidget:

MEM+ starts at exactly the bottom pixel of the band plan bar. Any hover over MEM+
immediately fires hideText() before Qt's tooltip timer can complete. DAX falls
in the waterfall zone where a similar suppression applies.

Suggested Fix

Guard every QToolTip::hideText() call in SpectrumWidget::mouseMoveEvent and
updateTrackedCursorState() with a childAt() check. If the cursor is over a
child widget, skip the hideText() call entirely -- the child owns the tooltip
at that point.

Example for mouseMoveEvent:

void SpectrumWidget::mouseMoveEvent(QMouseEvent* ev)
{
    // Let child widgets (e.g. SpectrumOverlayMenu buttons) own their tooltips.
    if (childAt(ev->position().toPoint())) {
        ev->ignore();
        return;
    }
    // ... existing code ...
}

The same guard should be applied to updateTrackedCursorState() before the
hideText() call at line 1654.

Acceptance Criteria

• Hovering MEM+ shows its tooltip for the full Qt default duration
• Hovering DAX shows its tooltip for the full Qt default duration
• MEM▶ tooltip continues to work
• Spot cluster tooltips and TNF tooltips in SpectrumWidget continue to work
• Band plan bar hover tooltips continue to work

Steps to reproduce

Steps to Reproduce

1. Open AetherSDR (radio connection not required).
2. Click → to expand the spectrum sidebar.
3. Hover over MEM▶ -- tooltip appears and stays.
4. Hover over MEM+ -- tooltip appears for ~0.5 s then disappears.
5. Hover over DAX -- same as MEM+.
