Use AuthTokenSection in App (build fails with TS errors) **** REVISE

COMMIT DESC ***

* package.json: add Nextcloud dependencies (from Nextcloud)
* 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:

     ERROR in [eslint]
     /app/src/components/AuthTokenSection.vue
       35:27  error  "@nextcloud/initial-state" is not published  n/no-unpublished-import
       36:32  error  "@nextcloud/l10n" is not published           n/no-unpublished-import

  I can only assume that that rule is disabled in the rule set we
  extend from or that the module resolution "node" can not find the
  files.

  The error actually complains about the module not being part of
  "dependencies" in package.json, which is the case, however.

  The internet calls for allowing such modules, which IMO defeats the
  purpose.

   The rule is also present in Nextcloud's core config.

----------------------

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
