Post-demo frontend fixes

[tchojnacki]

One task, since all of these require very low effort:

• [x] Sudoku is not randomized - we get the exact same board each time (reporter: @tchojnacki).
• [x] Register and login views are not scrollable when keyboard is extended (reporter: @jakubzehner).
• [x] Starting a particular game from the game list view is not intuitive - we should open the game screen when clicking a game on the list, and only leaderboard should be behind the menu, or maybe even it could just be entered through an icon (reporter: @jakubzehner).
• [x] Wordle does not correctly scroll down when entering new words (reporter: @jakubzehner).
• ❌ [WON'T FIX] Wordle input can skip a square when entering quickly (reporter: @Daxin18).
• [x] Empty profile list text doesn't fit on smaller screens, allow line breaks or decrease the font size (reporter: @tchojnacki, screen below).
• [x] SOS alert confirmation text in light mode has black font on black background (reporter: @tchojnacki, screen below).
• [x] Doubles are not allowed for amounts in medication, they return a confusing and wrong error message (reporter: @tchojnacki, screen below).
• [x] There's no gap between time and score in Sudoku view on smaller screens (reporter: @tchojnacki, screen below).

(comma doesn't work either)

• low effort fix: update the error message
• high effort fix: allow doubles, the backend supports them

No gap between text on some resolutions. There's a lot of free space below the grid, maybe use it instead?
