fix: EUPL licence tag, SPDX headers, getRequestToken, readonly constructors

Issues caught by every code review on apps built from this template:
- <licence>agpl</licence> → <licence>eupl</licence>
- OC.requestToken → getRequestToken() from @nextcloud/auth
- Added SPDX-License-Identifier: EUPL-1.2 to all PHP/JS/Vue files
- Constructor properties: private → private readonly
