feat(frontend): refresh dark theme + redesign login page

- Swap navy dark palette for VS Code Dark+ neutrals (#1e1e1e/#252526/
  #2d2d30) across theme tokens, page backgrounds and DateTimePicker
- Add brand header to the mobile drawer and desktop sider, and recolor
  the drawer body so it reads as one panel with the menu
- Redesign login page with a centered card, cycling Hello/Welcome
  headline and per-theme animated gradient-blob backgrounds
