Screenshot-matched layout fix

The PNG's visible top sits ~12 DIP below the workspace header border in the supplied screenshot. Root cause: 8-DIP sidebar top inset and about 4 DIP transparent visual edge inside the existing logo area.

• Sidebar top padding 8 → 0 only; left/right/bottom unchanged.
• Move the 68×70 brand image's layout box up by 4 DIP with a compensated bottom margin.
• The resulting visible PNG top aligns with MainWorkspaceHeader at the same Grid.Row 0.
• Preserve PNG source, image size, click targets, rail button vertical placement, and all existing layouts/styles. No asset, decoder or engine modifications.
• Add repository regression test for top alignment and preservation of Setup/Connect order and original 91 DIP first-button offset.

Verification

Require normal Windows PR checks before merge, then confirm master CI. A screenshot/OBS-C check is encouraged; this is a focused XAML-only change.
