keyboard & touch navigation, configurable settings, and refactor

- keyboard support: arrow keys or `hjkl` to move cursor, Space to start
  selection, Enter to confirm, Escape to cancel
- configurable settings: word placement directions, grid size, cell
  size, colors, fonts, debug mode, and more via `GameSettings`
- modernize CSS (logical properties, grid layout) and HTML semantics
- refactor JavaScript code around single-responsibility principles
