* feat(ios): mascot moods for onboarding and gateway quick setup
The activation glyph now takes a mood: the onboarding welcome step
shows the hard-hat working mascot while connecting, the success step
celebrates, and the gateway quick-setup header derives working/sad/
curious/idle from its connect state.
* fix(ios): quick-setup mood reflects app-level gateway problems too
The sheet renders two error surfaces — the local connect error and the
app-level gateway problem banner — and the mascot now goes sad for
either instead of only the sheet-local failure.
