[Bug] "Enter name manually" uses different layout and ignores 24-hour time format

[iamkartiknayak]

Issue/Description:
When enabling the Enter name manually option in COSMIC Greeter, the login screen switches to a different layout compared to the normal user-selection view. This causes two issues:

1. The greeter no longer follows the system’s 24-hour time format and instead displays time in 12-hour format (AM/PM).
2. The layout changes significantly, shifting the card UI instead of keeping a consistent structure. The default user icon is also not used, making the UI feel inconsistent & out of place.

For reference:

• Image 1: Normal user selection view (correct layout + 24-hour time)
• Image 2: Enter name manually view (different layout + 12-hour time)

The Enter name manually option should ideally reuse the same layout and default icon as user icon, with only the username field added by making spacer vertically by moving profile image and password field.

Version:

cosmic-greeter:
  Installed: 0.1.0~1769825079~24.04~d542978

Steps to Reproduce:

• Open COSMIC Greeter
• Enable or select Enter name manually
• Observe the time format and layout changes

Expected Behavior:

• Enter name manually should:
  • Respect the system’s 24-hour time setting
  • Use the same card layout as the normal user selection view
  • Use the default user icon instead of changing the visual structure

Other Notes:
UI consistency would improve usability and avoid visual jumps when switching login modes.
