Update dependencies to address security vulnerabilities

[PeterDaveHello]

Run npm audit fix to resolve multiple security issues:

• webpack 5.92.1 to 5.97.1 - mitigated XSS risk (GHSA-4vvj-4cpr-p986)
• elliptic 6.5.7 to 6.6.1 - fixed ECDSA validation (GHSA-fc9h-whq2-v747)
• katex 0.16.11 to 0.16.21 - patched HTML validation (GHSA-cg87-wmx4-v546)
• nanoid 3.3.7 to 3.3.8 - fixed predictable IDs (GHSA-mwcw-c2x4-8c55)
• cross-spawn 7.0.3 to 7.0.6 - partial ReDoS fix (GHSA-3xgq-45jj-v275)

Related dependency updates:

• @types/estree 1.0.5 to 1.0.6
• @webassemblyjs/ast and related packages 1.12.1 to 1.14.1
• browserslist 4.23.1 to 4.24.4

Reduces vulnerabilities from 7 (1 low, 3 moderate, 3 high) to 3 (high).

The remaining vulnerabilities require major version upgrades or involve manually breaking change handling to fully resolve the issues.

By the way, I manually built and tested the basic functionality of the Firefox version, and at least within the range of features I commonly use, everything works fine with no breaking chances.

@josStorer mind to take a look?
