Ensure consistent newline behavior in auto-height editors with JetBrains keymap (#47595)

Daniel Strobusch created 

Add an explicit `Editor && mode == auto_height` context block. This
ensures that `Shift+Enter` and `Ctrl+Enter` correctly insert a newline
at the cursor position in editors like the AI Agent Panel,
preventing them from inheriting conflicting overrides (e.g., JetBrains
mapping `Shift+Enter` to `editor::NewlineBelow`).

Closes #47269

Release Notes:

- Fixed an issue where `Shift+Enter` would insert a newline at the end
of the text instead of the cursor position in the Agent Panel when using
certain keymaps.
