Coinos v3: rebrand from Hal, payment addresses move to @coinos.io

The wallet is the next version of coinos, deployed at v3.coinos.io
(same build as halwallet.app) ahead of an eventual migration of
coinos.io itself. App name, manifest, notifications, and the NWC alias
all say Coinos; the Hal Finney tribute stays.

The registrar is multi-domain (per-domain Cloudflare zones; existing
halwallet.app names keep working) and new claims default to @coinos.io.
Names belonging to existing coinos users are reserved for them — the
registrar checks the live coinos API before granting a claim — until
the migration gives those users a way to claim their own.
