Make the GitLab CI jobs pass

Problem/Motivation

The first GitLab CI pipeline on 1.0.x passed, but four jobs that are allowed to fail reported problems:

• phpcs: one warning in gitlab_templates_version.txt, a file that the pipeline itself creates.
• ESLint: config/install/earkiv.settings.yml is empty, which the YAML rules do not allow (yml/no-empty-document). A new installation also starts without a default archiver and storage.
• cspell: unknown words such as Arkiv, earkiv, httrack, webimage, RRULE, DTSTART, BYDAY, BYHOUR, BYMINUTE, BYSECOND, pids and sitemapindex.
• phpstan: 13 errors, among them ten \Drupal calls in classes (ArchiveListBuilder, HTTrackCommands, HTTrackArchiver, LocalStorage) and a missing return type on ArchiveListBuilder::getDefaultOperations(). The two plugin managers use annotation discovery, which is deprecated in Drupal 11.2; that is handled in a separate issue for Drupal 12.

Proposed resolution

1. Exclude gitlab_templates_version.txt in phpcs.xml.dist.
2. Give config/install/earkiv.settings.yml the default archiver and storage and their default settings, matching the configuration schema.
3. Add .cspell-project-words.txt with the words of the module.
4. Inject the services instead of calling \Drupal in the classes that phpstan reports, and add the missing return type.

Each step is a separate commit. phpstan may still report the annotation discovery until the Drupal 12 issue is done.

Remaining tasks

• Implement and check the pipeline.
• Review.

User interface changes

A new installation has the HTTrack archiver and the local storage selected by default.

API changes

None.

Data model changes

Default configuration in config/install/earkiv.settings.yml. Existing sites are not affected.
