fix: refresh lock file to resolve vulnerabilities

Snyk (dev, all-projects): critical 2 -> 0, high 76 -> 6, medium 33 -> 8, low 6 -> 1
npm audit: critical 4 -> 3, high 40 -> 33, moderate 9 -> 10, low 4 -> 0

.talismanrc: package-lock.json now ignores filecontent and base64content
(sha512 integrity hashes; false positives).
