ClawPanel is the management tool - the docs should be about deploying
ClawPanel itself on Linux/Docker, not OpenClaw Gateway.
- Rewrite linux-deploy.md: ClawPanel Web版 Linux deployment guide
- Rewrite docker-deploy.md: ClawPanel Web版 Docker deployment guide
- Rewrite linux-deploy.sh: one-click script deploys ClawPanel Web + OpenClaw
- Update README deploy sections with correct descriptions and commands
- Update index.html deploy section and docs center card descriptions
- Port changed from 18789 (Gateway) to 1420 (ClawPanel Web)
