Switch faucet blockchain based on environment (Sepolia on DEV/LOC, Ethereum otherwise) and replace CHF-based amount conversion with a fixed native-coin amount (0.0005 ETH).
Match the readonly field style used in realunit.service.ts for environment-based blockchain selection.
Faucet is required for the BitBox RealUnit sell flow on Sepolia (DEV/LOC). Keep the ENV flag as an explicit override for PRD.
The flag is auto-enabled on DEV and LOC and only relevant on PRD, where it is configured via deployment secrets.

Needed for the upcoming BitBox (hardware-wallet) RealUnit sell flow: since BitBox02 firmware does not expose a raw EIP-7702 authorization signing API, BitBox users cannot use the gasless relayer path. Instead, DFX tops up the user wallet with a small fixed amount of ETH (enough for one ERC-20 transfer of REALU to the deposit address), so that the sell flow can be completed via the existing
