Stefan Haller 252a26cbc4 Hide the focused main view's selection when there's no diff to act on
The focused main view always showed a selection while it held focus, even when
its content was a placeholder ("No changed files", a merge-conflict message)
rather than a diff — so pressing a navigation key conjured a highlighted line
over "No changed files", and discarding the last change (or changes vanishing
outside lazygit) left a stale selection behind.

A selection should only show when there are change lines to act on. Two
moments establish or change the content:

- Focus: showInitialDiffSelection now leaves the selection off when the view
  has no change lines (ViewHasChangeLines), rather than highlighting a stray
  line at the top.
- Render: the side panel's render-to-main is where it decides between a diff
  and a placeholder, so that's where the selection's visibility is set —
  updateFocusedMainViewSelectionVisibility shows it only on the focused pane
  and only when a diff is being rendered. This covers the refresh cases that
  focus can't: discarding the last change, and changes disappearing or
  reappearing outside lazygit, all hide or restore the selection on the next
  refresh. (Focusing reuses the already-rendered content rather than
  re-rendering, which is why focus needs its own check.)

Wired into the files panel, where placeholders occur; the commit panels always
render a diff. Adds a SelectionIsShown/SelectionIsHidden test assertion.
