```
git_ui: Enable navigation for single-hunk diffs (#62615)

## What

Keep the hunk navigation controls available when a diff contains one
hunk, so users can return to it after scrolling away. This applies to
solo, staged, unstaged, and project diff views.

## Why

The controls were only rendered when `hunk_count > 1`, even though the
existing navigation actions already wrap and recenter a single hunk.

## How

Render the previous and next hunk controls whenever `hunk_count > 0`,
reusing the existing navigation actions.

Closes #62469

## Testing

- `cargo +stable-x86_64-pc-windows-gnu test -p git_ui --lib` — 130
passed.
- `cargo +stable-x86_64-pc-windows-gnu build -p zed -j 1` — passed.
- `rustfmt --edition 2024 --check` on the four changed files — passed.
- `git diff --check` — passed.
- Manually verified with the branch-built Zed on Windows: opened a
tracked file with exactly one diff hunk, expanded the context, scrolled
below the hunk, and used **Go to Previous Hunk**. The view returned to
the changed line.
