feat: expose license_tags to feed and license endpoints

[Copilot]

License taxonomy tags (e.g. "family:ODC", "license:open-data-commons") exist in the DB but were not surfaced via the API. This adds license_tags to all feed endpoints (under source_info) and to license endpoints.

API Schema (docs/DatabaseCatalogAPI.yaml)

• Added license_tags: string[] to SourceInfo schema → propagates to all feed endpoints
• Added license_tags: string[] to LicenseBase schema → propagates to LicenseWithRules and Licenses endpoints

Python Implementation

• license_base_impl.py: Extracts license_tags from license_orm.tags (the license_license_tags many-to-many ORM relationship)
• basic_feed_impl.py: Extracts license_tags from feed.license.tags, passes to SourceInfo

Example response shape:

{
  "source_info": {
    "license_id": "ODbL-1.0",
    "license_tags": ["family:ODC", "license:open-data-commons"]
  }
}

{
  "id": "ODbL-1.0",
  "license_tags": ["family:ODC", "license:open-data-commons"],
  "license_rules": [...]
}

Generated Code (regenerated, not committed)

• api/src/feeds_gen/ — regenerated from updated YAML
• web-app/src/app/services/feeds/types.ts — regenerated via openapi-typescript@6.7.6

Test Infrastructure

• populate_db_test_data.py: Added support for license_tag_groups, license_tags, and license_license_tags sections in test data JSON
• Integration test data: Added tag groups, tags (family:ODC, license:open-data-commons), and associations to license-1
• Integration tests: Updated license and feed tests to assert license_tags in responses

This section details on the original issue you should resolve

<issue_title>Expose the license tag information to the feed and license endpoints</issue_title>
<issue_description>### Describe the problem

Expose the license tag information to the feed and license endpoints.

Proposed solution

Expose the license tag to the feed endpoints:

• v1/feeds
• v1/feeds/{id}
• v1/gtfs_feeds/{id}
• v1/gtfs_feeds/{id}
• v1/gbfs_feeds
• v1/gbfs_feeds/{id}
• v1/gtfs_rt_feeds/{id}
• v1/gtfs_rt_feeds/{id}
  For those endpoints, the field to add is under source_info, for example:

{
...
"source_info": 
"license_tags": [
"family:ODC",
"license:open-data-commons"
]
...
}

Expose the license tag to the license endpoint:

• v1/license/{id}
  with structure:

...
"license_tags": [
"family:ODC",
"license:open-data-commons"
]
...
