cmd/bootstrap-chain: read LUX_MNEMONIC env (one var, one way)

Browse Source 
The earlier MNEMONIC unification commit (4383ad4) missed this CLI tool;
it was still reading the legacy MNEMONIC env name directly via
os.Getenv. Per the "one var, one way" rule the canonical name is
LUX_MNEMONIC across every code path in the genesis repo.

Updated in cmd/bootstrap-chain/main.go:
- Package-doc usage example: MNEMONIC="..." -> LUX_MNEMONIC="..."
- --print-addr-only flag help: scrub MNEMONIC -> LUX_MNEMONIC
- --key-file flag help + comments: MNEMONIC -> LUX_MNEMONIC
- loadKey() reads os.Getenv("LUX_MNEMONIC") instead of "MNEMONIC"
- Error message references LUX_MNEMONIC

No backcompat fallback: callers using the legacy MNEMONIC env get the
clear "LUX_MNEMONIC env var or --key-file required" error.

Verification:
- go build ./...           -> clean
- go vet ./...             -> clean
- go test ./... -count=1   -> ok configs, ok pkg/genesis
