Claude review: drm/panic: Fix panic logo alignment

[Claude Code Review Bot <claude-review@example.com>]

Patch Review

**Approach**: The patch adds a `drm_rect_translate()` call to horizontally center `r_logo` after it's initialized by `drm_panic_logo_rect()`. This is the same pattern used at line 502 for centering `r_msg`.

**Correctness**: Since `drm_panic_logo_rect()` initializes the rect at origin (0, 0) (see line 457), `r_logo.x2` equals the logo width, so `(sb->width - r_logo.x2) / 2` correctly computes the left offset for centering. The y-translation of 0 keeps it at the top.

**Potential type concern**: `sb->width` is `unsigned int` and `r_logo.x2` is `int` (from `struct drm_rect`). If the logo is wider than the screen, `(sb->width - r_logo.x2)` could produce a large unsigned value, resulting in a bad translation. However:
1. The same pattern is already used for `r_msg` at line 502 without a guard.
2. `drm_panic_logo_draw()` (line 468) already checks `rect->x2 > sb->width` and bails out, so a garbled rect would simply not be drawn.
3. In practice, panic logos are small relative to any screen.

So this is not a new issue introduced by this patch.

**Nit**: The commit message says "Fix panic logo alignment" which implies the current behavior is a bug. It might be more accurate to say "Center panic logo" since the left-alignment may have been the original intent rather than a bug. But this is subjective — if the intent was always to center it, "Fix" is appropriate.

**Verdict**: Looks good. The change is minimal, follows existing patterns, and improves visual consistency of the user-type panic screen.
