feat: single entry point routing — convert to front controller pattern

- Create app/public/index.php as front controller (bootstrap + Dispatcher)
- Rewrite app/router.php for PHP dev server → all non-asset requests to index.php
- Update Dispatcher to render full page layouts (head+header+view+footer)
- Move public view templates into templates/public/ (home, search, tfe, about, repertoire)
- Delete dead direct-access public/*.php files (apropos, search, tfe, licence, repertoire)
- Add clean URL routes to Dispatcher (/search, /tfe, /repertoire, /apropos, /licence, /media)
- Remove .php extensions from all internal links (header, views, templates, URLs)
- Update OG tags in controllers to use clean URLs
- Update nginx posterg.conf → front-controller try_files pattern, block direct .php access
- Update header.php and search-bar.php form actions to clean URLs
- Switch AboutController nav key from 'nav' to 'currentNav' for consistency

 - [ ] Update Dispatcher to handle all routes directly (no require APP_ROOT/public/*.php)
 
 ### Phase 2: Single entry point
-- [ ] Create app/public/index.php as front controller
-  - [ ] Bootstrap + Dispatcher invocation
-- [ ] Remove direct-access public/*.php (index.php, search.php, tfe.php, apropos.php, licence.php)
-- [ ] Rename old entry points so they can't be hit directly (e.g., prefix with underscore or delete)
+- [x] Create app/public/index.php as front controller
+  - [x] Move bootstrap logic into entry point (bootstrap.php stays for admin)
+  - [x] Load and invoke Dispatcher
+- [x] Move old public/*.php views into templates/public/
+  - [x] search.php → templates/public/search.php
+  - [x] tfe.php → templates/public/tfe.php
+  - [x] apropos.php → templates/public/about.php
+  - [x] repertoire.php → templates/public/repertoire.php
+- [x] Delete old direct-access public/*.php files
+  - [x] Delete public/index.php (replaced by front controller)

+- [x] Update Dispatcher to render full pages (head + header + view + footer) instead of requiring bootstrap
+- [x] Ensure admin/index.php bootstraps its own path (not affected by front controller)
 
 ### Phase 3: Server config
 - [ ] Update router.php — route all PHP requests to Dispatcher
 - [ ] Update nginx config — point all public routes to index.php via try_files
   - [ ] Replace per-file `location ~ \.php$` with front-controller pattern
-
-### Phase 4: Cleanup
-- [ ] Delete app/public/live-reload.php (already handled by LiveReloadController)
-- [ ] Test all routes (/, search.php, tfe, repertoire, apropos, licence, media, live-reload)
+- [x] Clean URL updates
+  - [x] Remove .php from all internal links (header, views, controllers)
+  - [x] Add clean routes to Dispatcher (/search, /tfe, /media)
+  - [x] Update og:url tags in controllers to use clean URLs
+  - [x] Update TfeController redirect to /
+  - [x] Update header.php action URLs
