WCAG 3.3.1: autofocus first invalid field on add/edit form validation failure

Browse Source 
Add App::flashAutofocus(fieldName) and consumeAutofocus() to the thin App
helper so action handlers can identify which field caused a validation error
and the form page can move browser focus directly to it on reload.

Changes:
- src/App.php — flashAutofocus() stores field name in _flash_autofocus
  session key; consumeAutofocus() drains it and returns the name (or null)
- actions/formulaire.php — catch block maps exception messages to field
  names (auteurice, titre, synopsis, année, orientation, ap, finality,
  languages, tag, lien) and calls App::flashAutofocus()
- actions/edit.php — catch block maps common edit errors to field names
  and calls App::flashAutofocus()
- add.php — consumes the hint via App::consumeAutofocus() into
  $autofocusField; withAutofocus() helper merges autofocus=>true into
  $attrs for every field include; synopsis textarea gets inline autofocus
- edit.php — same pattern with inline ternary merges and textarea autofocus
- templates/partials/form/text-field.php — $attrs loop now emits bare
  attribute names (no ="...") when value === true, supporting autofocus,
  disabled, readonly etc. without special-casing
- templates/partials/form/select-field.php — same boolean-attr support
  added; $attrs variable initialised to [] when caller omits it

Closes WCAG 3.3.1 autofocus item in todo/04-accessibility.md.

## 3.3.1 Error identification
- [x] **`add.php`/`edit.php` validation errors** — `flash-messages.php` already emits `<p role="alert" data-type="error">` for errors and `<p role="status">` for success
- [ ] **`add.php`/`edit.php` `autofocus` on first invalid field** — requires controller to pass back which field failed; deferred (larger refactor)
- [x] **`add.php`/`edit.php` `autofocus` on first invalid field** — `App::flashAutofocus(fieldName)` stores the failing field in `$_SESSION['_flash_autofocus']`; action handlers map exception messages to field names; `add.php` consumes via `withAutofocus()` helper + injects into `$attrs`; `edit.php` uses inline ternary; partials support boolean `true` in `$attrs` to emit bare attribute names
