Migrate template to OpenClaw (rename + new defaults)

[vignesh07]

Summary

Updates this Railway template to deploy OpenClaw (openclaw/openclaw) instead of the legacy Clawdbot repo/name.

Also adds an initial Debug Console in /setup (Option A) with an allowlist of safe actions + an advanced raw config editor.

Key changes

• Docker build now clones/builds openclaw/openclaw (arg: OPENCLAW_GIT_REF)
• Runtime wrapper calls openclaw and defaults to ~/.openclaw + openclaw.json
• UI routes updated to OpenClaw defaults (/openclaw)
• Template env vars renamed to OPENCLAW_* (with backward-compat support for existing CLAWDBOT_* env vars)

Setup UI improvements (Debug Console + Config Editor)

Inside /setup (password-protected):

• Debug console (no shell):
  • gateway.restart|stop|start (wrapper-managed)
  • openclaw status|health|doctor|--version
  • openclaw logs --tail N
  • openclaw config get <path>
• Raw config editor (advanced):
  • GET/POST the full config file (openclaw.json by default)
  • Writes a timestamped .bak-* backup on save
  • Restarts the gateway after save

Railway / deploy notes

• Wrapper still prefers an explicit public port env var and guards against Railway's default PORT behavior
• Healthcheck remains /setup/healthz
• Strongly recommend mounting a Railway Volume at /data and setting:
  • OPENCLAW_STATE_DIR=/data/.openclaw
  • OPENCLAW_WORKSPACE_DIR=/data/workspace

How to test

• npm install
• npm run lint
• (In Railway) deploy with a Volume at /data, set SETUP_PASSWORD, visit /setup, run setup, then open /openclaw
• Try Debug Console actions (restart, status, logs)
• Edit config (e.g. gateway.controlUi.basePath) and save; confirm restart + new route works
