fix: unify CSV import/export columns, fix import JS error, fix createThesis VALUES

- Fix createThesis SQL: extra ? placeholder in VALUES (27 values for 26 columns)
- Add createThesis integration tests to catch column/value mismatches
- Add CSV_COLUMNS as single source of truth in ExportController, deriving
  csvHeaders() and positional fallback from it
- Add missing columns to export query + CSV: duration_pages, duration_minutes,
  has_annexes, license_custom, contact_visible, objet
- Add missing columns to import INSERT: license_id, license_custom, cc2r,
  exemplaire_baiu, exemplaire_erg, objet, contact_visible, duration_pages,
  duration_minutes, has_annexes
- Resolve license name → license_id during import
- Fix XamxamInitFilePonds: add file-upload-filepond.js to admin-entry.js
  so FilePond initialization code is available on the admin list page
- Add FilePond vendor CSS to admin.min.css bundle (import dialog styling)
- Generate .admin-file-hint from csvHeaders() instead of hardcoded stale list
- Use positional fallback from CSV_COLUMNS for import cell parsing

 - [x] Simplify `tfe.php` HTML structure (remove `.tfe-layout` wrapper, remove `.tfe-synopsis-column` wrapper)
 - [x] Simplify `tfe.css` — replace flex-column with grid where possible, merge `.tfe-layout` into `.tfe-content-row`, remove dead wrappers
 - [x] Commit changes
+- [x] Remove "Mo" option from duration — keep only minutes and pages
+- [x] Combine pages and minutes as separate fields (both can be set simultaneously)
+- [x] Fix minutes input visibility (can't see what's typed)
+- [x] Add `has_annexes` checkbox to form + DB column
+- [x] Display duration on admin backoffice recap page
+- [x] Update public TFE page duration display for new combined format
+- [x] Fix `handleAutosaveResponse is not defined` — load `autosave-handler.js` on about_page edit view
+- [x] Fix `handleAutosaveResponse is not defined` in admin add/edit — function was scoped inside IIFE bundle, not on window
+- [x] Fix search result cards: title and author always below image/gradient, remove text overlay on placeholder gradient
+- [x] Change search results to 10 per page with HTMX pagination (no-JS fallback preserved)
+- [x] Bump to 15 results/page, make results area vertically scrollable, sticky pagination at viewport bottom
+- [x] Fix HTMX targetError: move #search-results wrapper inside fragment so it survives outerHTML swaps
+- [x] Add range counter to results header (e.g. "1–15 sur 112 résultats")
+- [x] Collapsible filter controls with <details>/<summary> + active filter badge on mobile
+- [x] Responsive paginator: hide first/last buttons on mobile, smaller touch targets
+- [x] Compact range counter on mobile: "1–15 / 112" instead of full "1–15 sur 112 résultats"
+- [x] Remove orientation display from search result card meta
+- [x] Add bulk select/delete to tmp cleanup dialog (like admin/index.php pattern)
+- [x] Move cleanup UI from modal to dedicated page (like add.php/edit.php)
+- [x] Replace <details> with <fieldset>/<legend> in cleanup fragments (like contenus.php)
+- [x] Standardise test group recipes: lint-php, lint-css, lint-js, test + add fix recipe + make lint pass clean
+- [x] Remove Mot de passe column from acces.php, add key.svg icon button in Actions to copy password to clipboard, reorder actions (URL/password/edit/toggle/archive), switch URL icon to link-simple.svg
+- [x] Fix CC2r: removed hidden seeds (were stale/overriding user input), render initial licence-choice from \$formData; Interne want_license unchecked clears CC2r+licence, switching from other modes preserves values; CC2r independent toggle; licence dropdown has no-licence placeholder
+- [x] Dans le formulaire admin, le contact privé ne se sauvegarde pas.
+- [x] Remove "Rendre le contact visible publiquement sur la fiche du TFE" from admin add/edit forms
+- [x] Auto-show contact on public TFE page when contact_visible is filled (no checkbox needed)
+- [x] Fix file size limits: align all layers (JS/FilepondHandler/ThesisFileHandler/validate-fragment) — video/audio 5 GB, default 500 MB, PDF 100 MB; fix JS fileValidateSizeFilter gate bug that rejected AV files >1 GB despite 8 GB per-ext cap
+- [x] Fix: deleting contact groups in apropos form not persisted (no change event after DOM removal, autosave never triggered)
+- [x] Improve h1, h2, h3 size difference in base.css heading scale
+- [x] Rework TFE page desktop layout: two columns 35vw/1fr, left = author/title/meta/synopsis, right = files, media 100% width; columns scroll independently, content fits 100vw; no bottom padding on main; add &scrollbar=0 to PDF iframe URLs
+- [x] 'Promoteur·ice ULB' remplacé par 'Promoteur·ice université' (changement juste l'étiquette)

+- [x] PDF viewer: render pages smaller by default (0.85× scale)
+- [x] PDF viewer: add dark transparent violet background behind pages when expanded
+- [x] pdf-viewer: expand to fill right column (not whole page), center pages, freeze column on expand
+- [x] pdf-viewer: fix toolbar width (align-self:stretch), hide sibling file items when expanded
+- [x] Fix createThesis SQL: extra `?` placeholder in VALUES (27 values for 26 columns) + add integration tests
+- [x] CSV import/export: single source of truth (CSV_COLUMNS), add missing columns (duration, annexes, license_custom, contact_visible, objet, cc2r, exemplaires), fix XamxamInitFilePonds → window.n, generate import hint from headers
