schema: Use generated dashboard model in frontend

[sdboyer]

What this PR does / why we need it:

Now that #54816 is in, we're actually finally ready to start using the generated dashboard types in the frontend omg omg omg ❤️ 🎉 🎊 🎉 ❤️

I figured i'd open this PR that just swaps in the type to get the ball rolling. Simply doing so produces almost 200 errors to be fixed :)

Maybe we end up figuring out a way to chunk it down, and we can close this PR. But i figured this was the easiest way for everyone to be able to see the TODO list.

Just updated this to make it a Partial<Dashboard>, at least initially. This reduces the set of errors to deal with down to 121 from 174 - slightly more tractable :)

With this change, on a quick scan, it looks like the only non-test file with errors is DashboardModel.ts itself. Almost every other test issue appears to be certain required fields being absent from panels. Seems like something that the exported defaultPanel const could probably help mitigate?

The bug mentioned above is fixed!

I don't understand the breaking changes because the reason seems to be removed label, type, and name of VariableModel, when they are not removed in fact. Do you have any idea what is happening here with this check @ivanortegaalba?

I took the liberty of moving this ts-expect-error here because I saw two errors from the typecheck:

public/app/features/dashboard/state/DashboardMigrator.test.ts:67:11 - error TS2578: Unused '@ts-expect-error' directive.

67           // @ts-expect-error
             ~~~~~~~~~~~~~~~~~~~

public/app/features/dashboard/state/DashboardMigrator.test.ts:70:13 - error TS2322: Type 'boolean' is not assignable to type '{ show: boolean; sort?: string | undefined; sortDesc?: boolean | undefined; }'.

70             legend: true,
               ~~~~~~

but now I sometimes see a fully successful pass of yarn typecheck and build the frontend successfully, and sometimes see some errors... I hope everything is alright, but please check one last time before you merge.

I experienced this problem as well. it seems to be a problem of how TS updates the cached results. If you remove from your local tsconfig.tsbuildinfo you will see the type check success deterministically.

It is because now the list templating variable is optional, so we're "removing" it because it was mandatory before.

Here is a PR to fix the issues with Enterprise https://github.com/grafana/grafana-enterprise/pull/4255

[ivanortegaalba]

After multiple changes, and manual testing of the modified runtime code. This PR is ready! ✅ Waiting for a second approval and I'll merge
