Add language-search component for Autre Langue input + active search in lists

Mirrors the mots-clé tag-search system: dropdown suggestions from
existing languages via HTMX, pill display with bin-icon remove buttons,
'Créer' option for new languages. Replaces the plain text input.

- New partial: templates/partials/form/language-search.php
- New fragment: public/partage/language-search-fragment.php
- Admin wrapper: public/admin/language-search-fragment.php
- Updated language-autre-fragment to return just the required asterisk indicator
- Updated both controllers to handle language_autre as array (pill-based)
  with backward-compatible string path
- Updated edit form to compute selectedOtherLanguages from DB
- Registered new route in partage/index.php
- Fix CSV importer: split comma-separated language column into individual entries
- Add htmx active search to admin index, title line-clamp, predefined languages only in checkboxes
- Admin index: filter form now uses htmx triggers (input delay:300ms on search,
  change on selects) to actively search without page reload
- Sort links include hx-push-url for back-button support
- Added loading indicator bar (.admin-search-indicator)
- Title column: line-clamp at 2 lines with overflow hidden, native title attr
  tooltip for full text
- Language checkboxes now show only 3 predefined languages (Français, Anglais,
  Néerlandais); all others go via the Autre langue search component
- Added Database::getPredefinedLanguages() and excluded predefined from
  language-search-fragment suggestions
- Included hidden sort/dir inputs in table-wrap so sort state preserved across
  filter changes
- Fix language-search: block 'Créer' for predefined languages in dropdown
  The 'Créer' option in the language-search dropdown now also checks against the
  predefined set (français, anglais, néerlandais) to avoid offering creation of
  languages that already exist as checkboxes.

+ *
+ * Replaces the old plain text input with an interactive component:
+ *   - Type to search among existing languages via HTMX
+ *   - If the language doesn't exist, a "Créer" option appears
+ *   - Selected languages are shown as pills with a round delete button (bin icon)
+ *   - All language names are lowercased and deduplicated
+ *
+ * Variables consumed:
+ *   string  $name             — base input name (hidden inputs will be name[]); default 'language_autre'
+ *   string  $label            — visible label text
+ *   string  $placeholder      — placeholder text for the search input
+ *   string  $hint             — optional hint shown above the input
+ *   string  $hxPost           — HTMX POST endpoint for language search
+ *   array   $selectedLanguages — array of ['id' => int|null, 'name' => string] for pre-filled languages
+ *   string|null $id           — override the id attribute prefix
+ *   int     $maxLanguages     — maximum number of languages (default 10)
