## Summary
- The dash separator and blinking caret in the sign-in 2FA OTP input had
hardcoded `black` and `white` background colors, making them invisible
in dark mode (black on black / white on white).
- Replaced with theme-aware colors (`theme.font.color.light` for the
dash, `theme.font.color.primary` for the caret) to match the existing
settings 2FA component.
## Test plan
- [ ] Open the 2FA verification screen in dark mode and verify the dash
between digit groups is visible
- [ ] Verify the blinking caret is visible in dark mode
- [ ] Confirm both still look correct in light mode
