[Rieven]

Changes

• This PR is a part of a larger PR.
• It implements POST request for OOIs selection (instead of GET)
• OOI selection will do a post request to report type selection (here you can view which OOIs you've selected)
• At report type selection page, you can go back to change selection (This is also done with a post request back to the OOI selection page.
• The other PR part 2 will implement the rest of the flow from report type selection posting to Setup scan/configuration page and saving report for viewing. Other pr: Part 2: Change report flow to POST request for Setup Scan and Saving report #3182

QA notes

Will only work for select oois (also works for select all) and next you will go to the report type selection page.
This PR stops there for post request. This is only step 1 which willl havdle only ooi selection and showing report type selection part.

I believe the work done in this particular PR works as intended as I've been able to verify that the mentioned actions are indeed POST requests. What doesn't work is going from the report selection to the next step. That results in an error. After consulting @Rieven I learned that this is indeed intended since that part will be fixed in Part 2 he mentioned above.

So as long as this doesn't get merged without part 2, QA seems all good.
