chore(webrtc-example): refresh lockfile and clear Next 16 audit findings

[Nisarg48]

Summary

• Update WebRTC example dependency lockfile for Next.js 16 (next@^16.2.5 → resolves to next@16.3.0)
• Remove npm overrides; refreshed package-lock.json so patched transitive versions resolve naturally
• npm audit reports 0 vulnerabilities after clean install
• Modernize tsconfig.json (target: ES2017, moduleResolution: bundler)

Notable package updates (resolved versions)

Package	Notes
next	16.3.0
axios	1.19.0 (via @benzinga/benzinga-squawk-sdk)
follow-redirects	1.16.0 (via axios)
postcss	8.5.23 (via next)
js-yaml	4.3.1 (eslint path); older 3.15.1 still present under Jest/babel
picomatch	4.0.5 and 2.3.2 both present (Jest/micromatch vs newer tooling)
@eslint/eslintrc	3.3.6
@typescript-eslint/*	resolves to 8.66.0

Direct dependency ranges in package.json are mostly unchanged; this PR mainly refreshes the lockfile and removes overrides that were previously used for Vanta/audit remediation.

Why overrides were removed

Parent packages/ranges now resolve to patched transitive versions without forcing overrides. Overrides can be re-added later only if Vanta/npm audit flags a transitive that the parent cannot upgrade yet.

• Spelling/grammar issue in the overview sentence: "icludes" should be "includes", and "which aims" should agree with the plural "applications".

Squawk is a realtime broadcast service from Benzinga which includes important headlines, price movement, and rumors as stories develop to give traders and investors news in the fastest and most convenient form. This repo icludes sample applications, which aims to elaborate how you can connect to Squawk.

• There are extra spaces inside the parentheses around "Chrome recommended".

- Access the demo page from your browser ( Chrome recommended )

• Extra space before the question mark in the heading makes the Markdown look unpolished.

### How to run the demo ?

• The resolved Next.js version in the refreshed lockfile requires Node >= 20.9.0. Adding an explicit Node engine constraint helps developers avoid confusing install/runtime failures when using older Node versions.

• The first bullet under "How to run" is missing terminal punctuation, which reads like an incomplete sentence.

- You need a valid Session, API Key, or JWT in order to run the demo. Please visit [the core API doc](https://docs.benzinga.io/benzinga/squawk-v4.html#Authenticate) on how to get a valid key
