feat: tag management tests, maintenance mode polish, répertoire pagination fix

- tests/Unit/DatabaseTest.php: tests 5-7 for findOrCreateTag round-trip, getUsedTags column, alias
- tests/Integration/SearchTest.php: tests 4-6 for tag subquery, full-text query, count consistency
- Database: getAllPublishedTheses() bypasses 100-row search cap for student index
- search.php: uses getAllPublishedTheses() for étudiantes column; all tests pass
