ux(setup): rewrite captive-portal + AP/setup-screen copy

Beta tester called the previous setup wording "Chinglish."
Tighter, plainer language across all three surfaces:

- Captive portal (PORTAL_HTML): "Connect your frame", explicit
  "Home WiFi name / Home WiFi password", clearer footer.
- AP screen step list: 5-line plain-English checklist; no more
  Safari-specific reference.
- Setup screen: fixed step 2 wrapping mid-domain
  ("pictureframe / .edholm.me"), tightened steps 1 and 3.

Regenerated bg.bin to match the new gen_screens.py output.
NEEDS-FLASH: in-field beta unit still has prior copy.
