The editor was overflowing its container because @uiw/react-codemirror
renders a wrapper div that doesn't inherit flex constraints by default.
Fixed by adding CSS rules that:
1. Set overflow:hidden on .cm-editor-container
2. Target the wrapper div (> div) with flex:1, min-height:0, overflow:hidden
3. Set .cm-editor and .cm-scroller to overflow appropriately
This ensures the flex height constraint propagates through every level
of the CodeMirror DOM tree, and only .cm-scroller scrolls.
Layout chain:
.cm-editor-container (flex-1, min-h-0)
└─ wrapper div (flex:1, min-h-0, overflow:hidden)
└─ .cm-editor (flex:1, min-h-0, overflow:hidden)
└─ .cm-scroller (min-h-0, overflow:auto) ← only this scrolls
