chore: eslint and dependency upgrade in the sdk

[isekovanic]

🎯 Goal

This PR resolves a couple of housekeeping tasks:

• Upgrade eslint and prettier to latest
  • This includes a migration to the new eslint.config.mjs format as well
  • It also includes reconciliation of rules that either got changed, removed or deprecated
  • It utilizes the new typescript-eslint configuration and all of its plugins and rules
  • An update of all eslint plugins as well
  • An update of styling in our SDK to reflect the new improvements better
  • Fixes in various places which were caught with the new rules (potentially even some very slight performance issues)
• An upgrade of the node runner for our SDK to 22.x
  • This includes an update of both variants of the SDK
  • It includes an update of various node related actions
  • It also includes an update of all sample apps

It is a follow-up of this change.
