feat(frontend): register, guide, feedback, addresses & status polling

- Add register screen with onboarding redirect to address validation
- Add waste separation guide screen with 4 categories and offline tips
  (organicos, reciclables, sanitarios, especiales) plus preventive
  messaging banner
- Add feedback submission screen with 4 types and 1-5 star rating
- Add address screen: list colonias, pick one, validate against backend
- Switch from pull-to-refresh GPS hack to periodic polling of
  /tracking/status (30s) — backend now drives the simulation
- Filter notifications by logged-in user.id (tunnel-view on client side)
- Add register/logout/address actions to profile screen
- Hide login/register/feedback/addresses from tab bar (href: null)
- Set API_URL to LAN IP for physical phone testing over hotspot
