Fetch cards using boards API with pagination rather than the .json backup endpoint

[mickzijdel]

Changes

1. Fetch the cards using the board API
2. Create a temporary list to hold orphaned cards

Context

I wanted to backup my Trello boards but for one board I got the following timeout error:

Unhandled exception. System.Net.Http.HttpRequestException: Response status code does not indicate success: 449 (Unknown).
   at System.Net.Http.HttpResponseMessage.EnsureSuccessStatusCode()
   at GoldenSyrupGames.T2MD.Cli.ProcessTrelloBoardAsync(TrelloApiBoardModel trelloApiBoard, CliOptions options, Dictionary`2 duplicateBoardSuffixes) in /path/to/repo/T2MDCli/Cli.cs:line 475

   at GoldenSyrupGames.T2MD.Cli.Main(String[] args) in /path/to/repo/T2MDCli/Cli.cs:line 47
   at GoldenSyrupGames.T2MD.Cli.<Main>(String[] args)

and when just fetching the failing board, I got this error:

Unhandled exception. System.Net.Http.HttpRequestException: Response status code does not indicate success: 504 (Gateway Timeout).
   at System.Net.Http.HttpResponseMessage.EnsureSuccessStatusCode()
   at GoldenSyrupGames.T2MD.Cli.ProcessTrelloBoardAsync(TrelloApiBoardModel trelloApiBoard, CliOptions options, Dictionary`2 duplicateBoardSuffixes) in /path/to/repo/T2MDCli/Cli.cs:line 333

Aborted (core dumped)

I couldn't figure out what it was, but after navigating to the URL manually, I got the following error:

"API::TooManyCardsRequested: Requested too many cards, please limit\n at checkLimits (/opt/service/app/api/1/mixins/cardsMixinFactory.js:53:31)\n at Object.fx (/opt/service/app/api/1/mixins/cardsMixinFactory.js:718:25)\n at handleRequest (/opt/service/app/components/handler/handleRequest.js:134:16)\n at addPaths (/opt/service/app/components/api.js:294:30)\n at getPathDependencies (/opt/service/app/components/transformer.js:111:9)\n at Function.all (<anonymous>:null:null)\n at transformMany (/opt/service/app/components/transformer.js:195:51)\n at Object.transformOne (/opt/service/app/components/transformer.js:222:25)\n at Object.fx (/opt/service/app/api/1/board/controller/getBoardController.js:372:34)\n at handleRequest (/opt/service/app/components/handler/handleRequest.js:134:16)\n at runHandlerWithRequest (/opt/service/app/components/handler/runHandlerWithRequest.js:40:24)\n"

I fed Claude the API docs and asked it to modify the code for me so that it would fetch all the cards in the board with pagination in batches of a 1000 (the limit). After a few attempts, it came up with this code, which solved the issue and I have now backed up the board.

I do not have full project context to know if these changes make sense (maybe they should be put behind a flag?) but I wanted to provide it to you in case you can easily incorporate it.
