The faucet_config and sui_doctor subtests were parsing host-side doctor
output for sui environment info (active address, env, faucet URL). This
fails in CI because sui is only installed inside the sui-playground
container, not on the runner host.

Changes:
- testFaucetConfig: get active address via env run sui client active-address
- testSuiDoctor: verify sui envs and active address via env run
- Add envUpPassed guard to testSuiDoctor (requires running containers)

The env run output includes efctl UI messages (banner, info lines,
completion message) alongside the actual 0x... address. Using
strings.TrimSpace captured all that text as the address, causing
the faucet to reject it with 422 Unprocessable Entity.

Use a regex (0x[0-9a-fA-F]{40,}) to extract just the hex address.

…tibility

Add recursive host-side line ending normalization during setup and a robust
container-side normalization step using sed on startup. This ensures all
.sh scripts use LF line endings, resolving the 'bash\r' execution error
on Windows hosts.

Also includes minor lint fix in docker_patch.go.
