Add username column

[owenherbert-catalyst]

This merge requests introduces a new username column for the attendees table. This new column can be toggled on/off with a new configuration setting. This column will also abide by the Moodle protectusername and userpolicies configuration. The attendees download file will include the new field when enabled.

What's been done?

• Add new username column to page and download file.
• Fix Codesniffer errors.
• New attendeesshowusernames config setting.

Testing instructions:

1. Install this plugin branch on a Moodle 4.5 site.
2. Create an admin user and a student.
3. Confirm new "Show usernames in attendees table" plugin setting exists. Set it to true.
4. Change the Moodle "protect usernames" security setting to true ({domain}/admin/search.php?query=protectusername).
5. Add username to "Show user identity" Moodle setting. ({domain}/admin/settings.php?section=userpolicies)
6. Create a test course.
7. Add F2F to the test course.
8. Enroll all users to the test course.
9. Create a F2F session.
10. Add all users to the F2F session.
11. Confirm all users appear in the attendees table and the columns are populated with data. Also check downloaded file.
12. Change the Moodle "protect usernames" security setting to true ({domain}/admin/search.php?query=protectusername).
13. Confirm that the username column disappears in the attendees table. (that moodle setting blocks username display). Also check downloaded file.
14. Undo step 12.
15. Confirm that the username column reappears in the attendees table. Also check downloaded file.
16. Run unit tests with vendor/bin/phpunit --testsuite mod_facetoface_testsuite.

Username is supposed to be protected as private data in normal circumstances. Can we please make sure this respects the protectusernames setting at the bare minimum?

[danmarsden]

But.. this should also really be a setting, not all sites will want to display username in this report.

[owenherbert-catalyst]

Thankyou for the feedback @danmarsden . I'll add a new setting for this feature and make sure it respects protectusernames.

[danmarsden]

That would only be a bare minimum - probably also worth looking at how the 'show user identity' setting works in user policies settings and if it would be more appropriate for this report to respect those settings. Personally I think it's better to allow an admin to opt in adding this field to the report.

Hi @danmarsden , could I please get your feedback for the latest changes to this one?

[danmarsden]

sorry - unlikely I'll get to this quick - as long as username is not exposed under normal circumstances you should be able find someone in the AU team to do a review.

Approved, I've just asked Owen to squash it down a bit, then I'll merge
