WaylandKeybinds: localized info panel with setup steps

- Info panel in the plugin modal: live status with the number of keybinds
  GNOME registered, the three setup steps and a button that opens
  Discord's Keybinds page (closes only the plugin modal, which otherwise
  blocks settings navigation).
- Follows Discord's language: English, Portuguese (pt-BR) and Spanish
  (es-ES and es-419 use each region's action names); bold labels quote
  Discord's own strings.
- Shared helpers moved to discord.ts; copy and locale choice in copy.ts,
  covered by basis-path tests (41 tests).
- README: current settings path (User Settings > System > Keybinds).
