Align window controls and compact the app frame

[brsbl]

Human comments

What was wrong

The right collapse control used a different inset from the panel controls below. Separate navigation alignment and wider padding made the frame feel uneven.

What changed

• Align the right collapse control above its panel-control column and group the left navigation controls.
• Reduce the rail from 52px to 44px and framed side/bottom padding from 12px to 8px.
• Reduce the top strip from 48px to 40px while preserving the controls’ vertical axis.

How you verified

• Remote CI passed for 50451ce6c17894a9c15c0c9a20915701e3b062a1.
• Chrome for Testing 155.0.8059.39: full-app reload, sidebar collapse/expand, and right-panel opening.
• User approved the layout. Rebase onto e9ad6b0e3473628f96fa98378cf8528aac8984d2 preserved all seven patches; fresh screenshots confirm the same geometry.
• Cumulative Slop Cop at 1cde8e10619e33ddf23d2994336cfa1657d7a0e9 found no P0/P1 issues. P2 follow-up: extend sidebar resizing through the footer edge.
• Native macOS traffic-light clearance and window dragging remain unverified; no connected Mac was available.

Captured from the compared branch web apps using the same empty-workspace fixture, route, interaction state, and viewport. Framed captures use a macOS bridge fixture in Chrome. The fixture host is offline, so model selection is unavailable.
