Editor Improvements and a Unified Help Menu

A round of improvements to how you select, resize, and place blocks in the editor, plus a new help menu that brings support into the app.

• Snap-to-align resizing. As you resize a block, its edges snap to neighboring blocks and section boundaries, so blocks line up cleanly without nudging them pixel by pixel.
• Select blocks behind others. When blocks overlap, hold ⌘ (or Ctrl) and hover to reveal the one underneath, then click to select it — no need to move the top block out of the way.
• Redrawn selection handles. Selected blocks show a cleaner selection frame whose drag and resize handles stay locked to the block as you scroll, so the handle is always exactly where you expect it.
• Quick section trimming. Double-click a section's height handle to trim it down to fit its content, instead of dragging the edge into place by hand.
• Smarter block placement. New blocks now drop into the section you're actually working in — the one selected or most visible on screen — and are positioned sensibly within it, rather than landing in a fixed spot.
• Simpler layering shortcuts. Bring a block to the front or send it to the back with ⇧] and ⇧[.
• A unified help menu. A new help button in the dashboard and editor sidebars gathers support articles, contact support, feedback, keyboard shortcuts, and system status in one place — press ⌘K to search and read support articles without leaving your work.
