Add test coverage for remaining controllers, fix label accessibility, refactor duplicated code

New tests (47 added, 622 total):
- MonitorMessengerCommand: no failures, failures with email, null error, multiple (4)
- UnsubscribeController: unsubscribe with invitations refused + admin notified (1)
- AdminController: suspend/reactivate orga, orders page with filters, logs, invite orga submit/empty, delete/resend invitation, export CSV/PDF (13)
- AccountController: export CSV/PDF, getAllowedBilletTypes (free/basic/sur-mesure/null), billet type restriction, finance stats all statuses, soldCounts (9)
- HomeController: city filter, date filter, all filters combined, stock route (4)
- OrderController: event ended, invalid cart JSON, invalid email, stock zero (4)
- MailerService: getAdminEmail, getAdminFrom (2)
- JS: comment node, tabs missing panel/id/parent, cart stock polling edge cases (10)

Accessibility fixes:
- events.html.twig: add for/id on search, city, date labels
- admin/orders.html.twig: add for/id on search, status labels

Code quality:
- cart.js: remove dead ternaire branch (max > 10 always plural)
- tabs.js: use optional chaining for tablist?.setAttribute
- MeilisearchConsistencyCommand: extract diffAndReport() (was duplicated 3x)
- Email templates: extract _order_items_table.html.twig partial
- SonarQube: exclude src/Entity/** from CPD
