fix(core/bootloader): fix bootloader warning icon placement on Safe 3
[no changelog]
What changed, and why it matters
This commit fixes a visual layout bug in the Trezor Safe 3 bootloader. A warning icon was being placed at the top-left of the screen instead of the top-right. The change simply moves the icon to the intended corner. There is no security issue here—only a cosmetic correction.
No security action needed. Treat as a normal UI fix.

Evidence from the diff
In core/embed/rust/src/ui/layout_caesar/bootloader/intro.rs, the bootloader intro screen rendered ICON_WARN_TITLE using shape::ToifImage::new(area.top_left(), …).with_align(Alignment2D::TOP_RIGHT). The position and alignment were inconsistent: the image was anchored at top-left but aligned to top-right. The patch changes the anchor to area.top_right() so the icon is correctly placed in the top-right corner on the Safe 3 (Caesar layout). This is a UI positioning fix with no functional or security implications.
