Rebrand: hal → coinos v3

The app already presents as Coinos; this finishes the job in the repo:
package name, README, GitHub link, code comments, and the stale locale
lines that still explained the old "Hal Wallet" name (they fall back to
the English tribute line). Kept: the hal-nwc-pouch IndexedDB name (an
upgrade-compat identifier), the halwallet.app domain in the BIP-353
names feature (live infrastructure), and the Hal Finney tribute itself.
