refactor: unify edit mode Format+Fichiers with add/partage HTMX fragment

- Edit mode now uses the same fichiers-fragment.php as add and partage,
  instead of duplicating the format checkboxes + new-file upload + website
  URL fieldsets.
- Edit-only elements (existing files list, cover replace) stay in
  a separate #edit-existing-files-block below the shared fragment.
- Removed .zip/.tar/.gz from the main TFE upload accept in both
  fichiers-fragment.php and fieldset-files.php. Archives go only
  in the Annexes file input.
- Removed admin/format-website-fragment.php dependency from edit
  (no longer needed — the shared fragment handles website too).

fix: jury repop crash + hx-preserve on file inputs, remove zip/tar from tfe accept

- Jury fieldset add-mode repopulation now handles both scalar (legacy)
  and array (new dynamic multi-row) values for jury_promoteur and
  jury_promoteur_ulb_name. htmlspecialchars() was choking on array value.
- All file inputs in fichiers-fragment.php wrapped in hx-preserve
  containers so HTMX swaps don't wipe user-selected files when toggling
  formats or the annexes checkbox.
- Removed .zip/.tar/.gz from main TFE file accept — archives only via
  annexes input (which already had multiple + correct accept).
- Edit mode now reuses the same fichiers-fragment.php fragment.

fix: file inputs re-initialize after HTMX swap via inline script

- Exposed window.XamxamInitFileUploads from file-upload-queue.js IIFE
  so HTMX fragments can trigger re-binding without a global listener.
- fichiers-fragment.php emits <script>XamxamInitFileUploads()</script>
  at the end of the #format-fichiers-block fragment.
- Removed hx-preserve wrappers — they prevented re-render after
  format/annexes toggles changed visible inputs.
- This also fixes .zip removal from TFE accept and jury repopulation
  array crash from the previous commit.

refactor: simplify file-upload-queue.js, remove file-preview.js

- file-upload-queue.js rewritten from ~250 lines to ~120 lines:
  no more DataTransfer machinery, no IIFE wrapper, uses .onchange
  instead of addEventListener for simpler HTMX re-init.
- window.XamxamInitFileUploads is the function itself (not an IIFE export).
- Merged file-preview.js functionality into file-upload-queue.js
  (single-file .data-preview handling). Deleted file-preview.js.
- fichiers-fragment.php inline script calls XamxamInitFileUploads()
  after every HTMX swap (same as before).

debug: add console.log to file-upload-queue.js for file input behavior

Adds logging at key points to diagnose why only one file is displayed:
- XamxamInitFileUploads called
- TFE queue picker init (id, multiple attribute state)
- onchange event (files count, names)
- fileArray post-concat length
- Single-file preview bindings (id, multiple attribute)

Remove after debug session.
