Pontoporeia 7d96a08324 perf: replace fat-view student index query with lean getPublishedAuthors()
The répertoire page was loading the full v_theses_public view
(15 JOINs + 8 GROUP_CONCAT temp B-trees) via getAllPublishedTheses()
just to build the student name → thesis-id map on the index page.
Only two columns (id, authors) were ever consumed by the template.

Add Database::getPublishedAuthors(): array
- Queries thesis_authors JOIN authors directly on the theses base table
- Filters on theses.is_published = 1 using the existing index
- Returns only id + GROUP_CONCAT(authors) — no view expansion
- Results verified identical to the old getAllPublishedTheses() output

Update search.php to call getPublishedAuthors() instead.
Mark getAllPublishedTheses() @deprecated in Database.php.

All tests pass.
