Improvements to ORT run results pages

[Etsija]

Features not implemented yet by closing of #680 or pending:

• logs of the run: streaming
• issues list, depends on Add endpoint to get issues of ORT run #405
• vulnerability list, ui: Show vulnerabilities #988
• rule violation list, depends on Add endpoint to get rule violations of ORT run #795

Ideas from the frontend alignment meeting 27.8.2024:

• show badge next to menu items, e.g., for vulnerabilities, show the number of vulnerabilities (and maybe by severity, with different badge colors)
• move issues to separate page, ui: Move issues of an ORT Run to a separate page #959
• move job details to separate page (in technical section of the sidebar), ui: Move job details #917
• traffic lights in run index page could link to technical section with the right job selected, Clicking on a (finished) job status circle should take me to that job's results #643, ui: Move job details #917
• show only summaries in overview page, like number of issues by severity
• show some statistical data in the overview page, e.g. a pie chart with number of projects per package manager
• show item next to menu items where data is still being generated, e.g. a spinner if the evaluator job is still running, or another item if it did not even start yet
• maybe show traffic lights in overview page, because users know it from the ort runs list, ui: Include traffic lights in ORT Run results page #936
