Add PigBank app

[acidio]

Summary

Adds PigBank, a kids' allowance app (pigbank.com.br, Brazilian Portuguese). The panel shows the child's piggy bank ("cofrinho"):

• The first name and balance, with a slow blinking "MESADA HOJE!" reminder on allowance day.
• One screen per savings piggy: amount saved, closed eyes + "Zz" while coins are locked, and the piglets (interest) due at the next allowance.
• The whole cycle stays within about 15 s.

Parents generate a key in the PigBank app (Ajustes → Painel) and paste it into the app's "Chave do PigBank" field. The key only reads that one child's data, and parents can revoke it at any time. Without a key, the app shows a "COLE A CHAVE" (paste the key) screen.

• One HTTPS GET to https://pigbank.com.br/api/panel/cofrinho with the key as a bearer token, cached 60 s
• No other network calls; 1x only (64×32)

Test plan

• pixlet check apps/pigbank
• Rendered with real data and with demo data
• Invalid / revoked key and no connection show their own screens instead of failing
