editor: Fix bracket colorization with folds and large functions (#51108)

Closes #47846

`visible_excerpts` computed the visible buffer range by adding display
line count directly to the buffer start row:

```rust
// Before
multi_buffer_visible_start + Point::new(visible_line_count, 0)
```
This ignores folds entirely. When a 700-line function is folded into one
display line, content after the fold is visible on screen but falls
outside the computed buffer range, so its brackets are never colorized.

The fix converts through display coordinates so the fold/wrap layers are
respected:

```rust
// After
let display_end = DisplayPoint::new(display_start.row + visible_line_count, 0);
let multi_buffer_visible_end = display_end.to_point(&display_snapshot);
```
