Merge long going React Migration Branch to master

[RobertSchueler]

We should not have a master branch and a React Migration branch developed next to each other. So we need to merge the React Migration Branch.
I did the following:

• rebased React Migration branch
• signed unsigned commits
• added some changes mentioned in comments here: Version updates approach2 #130

[Copilot]

Pull Request Overview

This PR merges the long-running React migration branch into master, rebases and cleans up unsigned commits, and aligns components with React Router v6 and updated utilities.

• Introduces React Router (router.tsx) and updates the app entry point to use RouterProvider.
• Refactors runtime formatting utilities and removes legacy view components.
• Establishes a repository abstraction for JSON-backed report and tag data.

• Component functions should be PascalCase. Rename casesTable to CasesTable to match React conventions.

export function casesTable(props: CasesTableProps) {

new/src/components/Scenarios/ScenarioHead.tsx:27

• The new millisecond display via addRuntimeInMilliseconds isn’t covered by tests. Consider adding unit tests for sub-second durations to ensure this behavior remains correct.

                        ? addRuntimeInMilliseconds(scenario.scenarioCases[0].durationInNanos)

The variable name treshhold is misspelled. Consider renaming it to threshold to match common terminology.

Suggested change

	treshhold: number,
	divisor: number,
	unitOfMeasure: string
	): string {
	return durationInNanos > treshhold
	threshold: number,
	divisor: number,
	unitOfMeasure: string
	): string {
	return durationInNanos > threshold

getReport casts only jGivenReport to JsonReport but the tagFile field on JsonReport is never populated. Consider returning both scenarios and tagFile together or update the interface.

Suggested change

	return jGivenReport as unknown as JsonReport;
	return {
	scenarios: jGivenReport.scenarios.map(r => r as ReportModel),
	tagFile: tagFile
	};

Uhh boy,
that is so much code to look through.

I don't think I can make an accurate assesment of the code (lack of time) and would suggest fixing forward after merch.
Hower for that I would like to not have skipped tests. Currently we are skipping twe entire test suits. Can we change that?
