Migrate ESLint config

[Justus-at-Tazama]

As a Tazama contributor,
I want an automated way to validate my contributions in terms of code style and linting rules,
So that I can write code that will be acceptable to the Tazama community

Acceptance Criteria

1. Migrate the implementation of ESLint from pre-v9 to post-v9 as per https://eslint.org/docs/latest/use/migrate-to-9.0.0#-new-default-config-format-eslintconfigjs
   Update: Decided on v8 for plugin support. Which is a flat config file for simple upgrade path when v9 is ready
2. Replace the deprecated module "eslint-config-standard-with-typescript": "^43.0.0", with the replacement "eslint-config-love": "^51.0.0", as per https://www.npmjs.com/package/eslint-config-love
   3. 3. Add eslint-plugin-promise and eslint-plugin-import
3. Add a rule top the linting to prevent module-scale linting overrides, if possible
   Update: Will require comment justification for inline eslint-disable rules, warning for now, error in future
4. Replace the "license": "ISC", in the package.json with "license": "Apache-2.0",
5. Ensure existing linting rules are migrated to the new "flat file config" in eslint.config.js
6. Run npx eslint to confirm linting is working as before (regression testing)
