FOR-813 Upgrade to Node 24

[leonardobishop-hmpo]

• Upgraded deps to latest (except redis, connect-redis, and express), set engine to 24 in package.json & CI
  • Upgrading redis and connect-redis causes issues in downstream apps as there is a new API: https://github.com/redis/node-redis/blob/master/docs/v4-to-v5.md#the-new-api-for-v5
• Updated import for sinon-chai following upgrade
• Manually added the Pragma header in nocache middleware since the nocache package no longer adds it in the latest version
• Updated get in logger to not increment level since it was failing eslint checks

Pull request overview

Updates the project to target Node.js 24 and aligns runtime/dev dependencies and small compatibility shims with the upgraded ecosystem.

Changes:

• Bumped Node engine/CI matrix to Node 24 and added .nvmrc.
• Upgraded dependencies (notably connect-redis, nocache, redis, chai/sinon toolchain) and adjusted imports accordingly.
• Added explicit Pragma: no-cache header in nocache middleware and adjusted tests; updated logger get() to avoid pre-increment.
