Use AuthTokenSection in App (fails with two kinds of TS errors)

* package.json: add Nextcloud dependencies (from Nextcloud)
* main.ts: register pinia

  Otherwise the following error would be thrown:

     TypeError: Cannot read properties of undefined (reading '_s')
         at i (pinia.mjs:1714:20)
         at setup (AuthTokenList.vue:11:32)
         at mn (vue.runtime.esm.js:3033:30)
         at vue.runtime.esm.js:2457:27
         ...

* remove .ts suffix from import paths (causes build error otherwise)
* add declare global to define Nextcloud types. This should be changed
  to @nextcloud/typings.
* annotated import of Nextcloud components (JS) with @ts-expect-error
  to solve tsc errors. This is most likely due to missing type
  definitions. Unclear how Nextcloud core made this working.
* the eslint rule set @nextcloud/eslint-config/typescript was added to
  prevent import path errors

The build fails with errors like

   ERROR in /app/src/components/AuthTokenSetup.vue.ts
   47:9-14
   [tsl] ERROR in /app/src/components/AuthTokenSetup.vue.ts(47,10)
         TS2339: Property 'reset' does not exist on type 'CreateComponentPublicInstance<{}, { authTokenStore: Store<"auth-token", { tokens: IToken[]; }, {}, { updateToken(token: IToken): Promise<any>; addToken(name: string): Promise<ITokenResponse | null>; deleteToken(token: IToken): Promise<...>; wipeToken(token: IToken): Promise<...>; renameToken(token: IToken, newName: ...'.

This hints at Typescript not being able to infer types from the
component definition.

Related issues:

* vuejs/vue#9873
* vuejs/vue#12628
* vuejs/vue#8721

Unsuccessfully attempted proposed solutions:

* Declaring return types on methods like:

  reset(): void {
  async submit(): Promise<void> {

* Using arrow functions

  Did not work and would introduce new errors anyway

* Defining interfaces for the returned component

  Caused another rabbit hole of more and more required type
  definitions, that should be infered by the Vue typings anyway
