NO-JIRA: Convert useTechPreviewFlagProvider to static function

[logonoff]

(s3e5 "Initiation")

window.SERVER_FLAGS is generated by the backend server and is known to not change. Thus, we do not need a hook and ReactNode for this flag, and we can simplify this to a simple console.flag for performance

📝 Walkthrough

Walkthrough

This pull request refactors the tech preview feature flag initialization in OpenShift Console. The change migrates from a hook-based provider pattern (useTechPreviewFlagProvider) to a handler-based pattern. A new tech-preview.ts module exports a FeatureFlagHandler that sets the FLAG_TECH_PREVIEW flag based on window.SERVER_FLAGS.techPreview. The console extensions configuration is updated to reference the new handler, the package.json exports are adjusted to point to the new module, and the legacy hook module is removed. The underlying flag-setting logic remains functionally equivalent.

In `@frontend/packages/console-app/src/features/tech-preview.ts`:
- Around line 4-5: The current handler sets FLAG_TECH_PREVIEW from
window.SERVER_FLAGS.techPreview which can throw if SERVER_FLAGS is undefined;
update the handler (function name: handler) to defensively read the flag using
optional chaining and a default false (e.g., base the value on
window.SERVER_FLAGS?.techPreview || false or
Boolean(window.SERVER_FLAGS?.techPreview)) before calling
setFeatureFlag(FLAG_TECH_PREVIEW, ...), ensuring no runtime TypeError when
SERVER_FLAGS is missing.
