fix(iso-visuals): harden panel indicator + auto-apply wallpaper on join

- Panel indicator: add have() checks for nc/python3, warn on missing
  deps instead of failing silently, distinct states for socket-down
  vs no-response with actionable tooltip text
- Join Hive: generate and apply identity wallpaper on success as
  visual 'you're in' confirmation via xfconf-query
- SKILL.md: document new behaviors
