feat: Panorama skill HUD and menu, CSS 1.0.375

- Skill card and W/S/E target menu drawn as CCSCustomHudLayout panels via PanoramaManager
  (panorama/ sources), replacing PrintToCenterHtml and WASDMenuAPI; WASDMenuAPI.dll dropped
- Custom status lines (cooldowns, charges) overwrite the description on the card; Medic keeps its
  description with the charge count below
- css_setoverride toggles a per-player cooldown bypass
- YourSkillChatInfo also gates the round-start skill description in chat
- Language: "[css_useSkill]" becomes the configured button name, "Press ... key" wording,
  welcome message trimmed to its first line
- Build against CounterStrikeSharp.API 1.0.375
