fix(render): handle permission errors when running as non-root user

- Check if CLAWDBOT_STATE_DIR or /data/.clawdbot is writable
- Fall back to $HOME/.clawdbot if permissions fail
- Update CLAWDBOT_STATE_DIR export to match actual directory used
- Prevents Docker failures when running as node user (non-root)
