fix: license, security vulnerabilities, and XSS hardening

- Replace all AGPL-3.0-or-later SPDX headers with PMPL-1.0-or-later (427 files)
- Replace AGPL LICENSE file with PMPL-1.0-or-later text
- Remove dead `getWriter` function in cli.zig (dangling stack reference)
- Fix temp file symlink attack in gossamer-integration-test.sh (use mktemp)
- Fix executeSSH command injection: change from raw string to argv slice,
  add `--` separator so SSH bypasses the remote shell entirely
- Add escapeXml() helper to fli-gauge.js; escape label before SVG injection
- Add escapeHtml() helper to fli-tooltip.js; escape data-tip attribute values
- Clear test credentials: cluster_password and rcon.password use empty strings

Panic-attack results: 0 critical (was 1), tainted paths 0 (was 8), 19 weak points (was 21)
