[Chore] Experiment page bundle refactoring

[ke4]

Most of the code that can be found under the experiment page bundle in the Single Cell Expression Atlas repository is not belongs to that repository. It should be moved to the atlas-components repository by creating 1 or more new components and creating a wrapper around that code in the single cell repository and render it.
There are 3 subtask for this story:

• move the code from the atlas-web-single-cell repository under app/src/main/javascript/bundles/experiment-page folder to the atlas-components repository and creating 1 or more new components as it fits
• clean the code: make it easy to maintain, testable, understandable by anyone. I added an example yesterday in Slack. (https://ebi-fg.slack.com/archives/C9P2QETJ9/p1726071369031389)
• creating a wrapper in the single cell repository in the app/src/main/javascript/bundles/experiment-page folder around the new code and render it
