fix(DTFS2-7375): codebase dependencies vulnerabilities

Introduction ✏️

This PR addresses reported vulnerabilities by triaging GitHub code scanning alerts related to various package dependencies, necessitating either minor or major version updates.

To ensure effective updates, I have removed the root package-lock.json 📦, which caused some related errors. This PR aims to resolve these vulnerabilities 🛡️, enhance code readability 📚, and significantly reduce duplicated code in libs/common, particularly around MongoDB connectivity.

Resolution ✔️

Dependency Updates: 📦 Updated several dependencies to their latest versions.
TypeScript Configuration: 🛠️ Standardized TS config to ES2018 to leverage named capture groups in RegEx.
MongoDB Refactor: 🗄️ Introduced a streamlined MongoDB driver class in libs/common to adhere to DRY principles, eliminating redundant code and arguments for MongoDB initialisation.

The new approach allows for a simple, two-line MongoDB initialisation as shown below:
```
import { MongoDbClient } from '@ukef/dtfs2-common/mongo-db-client';

const mongoConnection = new MongoDbClient();
```

This enables any microservice to either use an existing connection or establish a new one to the specified MongoDB database, reducing the number of threads required for new connections from different microservices or independent applications (e.g., utils/**).

Commonized MongoDB Connection Types: 🔄 Consolidated MongoDB connection status types under libs/common.
Improved Test Coverage: 🧪 Added epochDate to the utilisation-report.controller Jest test to handle null values correctly for the Date type.

Miscellaneous ➕

Removed Redundant package-lock.json Files: 🗑️ Eliminated unnecessary package-lock.json files due to DTFS's adoption of NPM workspaces.
Node & NPM Updates: ⬆️ Updated node to >=22.8.0 and npm to >=10.8.2 across all package.json files.
Environment Variable Addition: 🌐 Added ENVIRONMENT variable to the database (MSSQL) step for accurate GitHub environment referencing.
New type-check:all Script: 🧹 Added to housekeeping for comprehensive type-checking across the codebase.
Improved Documentation & Readability: 📝 Enhanced overall documentation and code clarity.
Logger Migration: 🔄 Replaced custom logger utility with native console due to unicode interpretation issues in Azure logs.
Standardised Console Logs: 🛠️ Minor adjustments to console logs for better debugging and troubleshooting in Azure.
Environment variables: Added missing Mongo specific environment variables in .env.sample.
DRY: Ensure libs/common constants are used for Portal values.
MongoDB: Introduced MONGODB_URI_LOCALHOST for test suite execution with MongoDB localhost connection string.
Formatting: Numerous formatting fixes across myriads of files.
GitHub Actions: I have updated all plugins to the latest version to ensure compatibility with the most recent Node.js release.
