Reporting: Move all CSV exports to endpoint (server) exports

[nagpai]

We currently have browser export for list report rows less than 25 ( pagination limit ) and server based export for rows more than that. Changing all exports to server via endpoint will help simplify our CSV exports and manage this functionality at one place.

Acceptance criteria

• All exports for Transactions, Payouts and Disputes - whether less than 25 rows or more - should be handled via server
• Tests should be updated to reflect this change

Details / subtasks

We've decided to implement a polling mechanism so merchants can download CSVs directly in the browser UI, and don't have to use email to access (unless they prefer that).

We initially attempted to generate and access the server-side export synchronously, if the rows were less than 25, but were unable to do so in the live environment, due to write permissions to the uploads folder on server made available to the async queue processor. We then decided to queue the download, and then use the Job Id to poll and check for the download file for 1 + 5 retries, each 1 sec apart. Email continues to remain a fall back option. ( ref - pMz3w-llm-p2#comment-124146 )

Overall, this will preserve the existing "immediate download" experience, similar to the UI for exporting small CSVs (< 25 rows).

• https://github.com/Automattic/transact-platform-server/issues/7172 provide server CSV API endpoint to allow polling, and provide access to the file when ready https://github.com/Automattic/transact-platform-server/pull/7154
• Transaction CSV exports should use export functionality from server #10255 - implement immediate download of Transactions CSVs in plugin, using polling mechanism
• https://github.com/Automattic/transact-platform-server/issues/7187 -
• https://github.com/Automattic/transact-platform-server/issues/7188 -
• TBD issue - implement immediate download of all other CSVs in plugin, using polling mechanism
• potentially other tasks, e.g. for different kinds of CSVs

Adding blocked status for now since we are not merging changes related to this issue until we have had adequate feedback on the project thread.

[haszari]

Removing blocked since @jessy-p has a sweet PR up with a fix:

• https://github.com/Automattic/transact-platform-server/pull/7154

FYI @nagpai @jessy-p Updated this to an epic, as it covers the main feature we need to ship, and can be broken up (server + client side x each CSV / list screen).

@haszari it looks like you forgot to removed blocked.
I've also moved to In-Progress rather than in-review.

Thanks @brucealdridge 🙌
