Security: Update transitive dependency resolutions

[github-actions]

Summary

Automated update of resolutions in package.json to fix vulnerable transitive dependencies.
Sources: Dependabot alerts (medium/high/critical) + yarn audit.

Changes

Dependency	Before	After	Severity	Source
brace-expansion	^2.0.2	^2.0.3	moderate	yarn-audit
node-forge	^1.3.2	^1.4.0	high	yarn-audit
path-to-regexp	^0.1.12	^0.1.13	high	yarn-audit
picomatch	(none)	^4.0.4	moderate	yarn-audit
serialize-javascript	^7.0.3	^7.0.5	moderate	yarn-audit
yaml	(none)	^1.10.3	moderate	yarn-audit

Note: This only updates transitive dependencies via resolutions. Direct dependency upgrades should be done manually to avoid breaking changes.
