search.php: semantic HTML overhaul of répertoire index and results view

- Replace 4x <div class="repertoire-col"> with <section>; remove
  .repertoire-col__header class, CSS now targets section > h2
- Wrap all index link groups in <ul>/<li>; delete the four per-column
  link classes (year-index-item, cat-index-item, student-index-item,
  keyword-index-item); active state switches from .active to
  aria-current="page" on the <a>
- Add <h1 class="sr-only">Répertoire</h1> so the index view has a
  page-level heading (WCAG 2.4.6)
- Remove redundant <div class="search-results-view"> wrapper; padding
  moved to .results-grid and .search-results-header directly
- Replace <div class="results-grid"> with <ul class="results-grid">;
  each result card becomes <li><a class="result-card">
- Replace <span class="result-card__meta"> with <small> (ancillary
  metadata per HTML spec)
- Replace result-count <p> with <output role="status"> (computed value)
- Replace 3x <div class="search-filter-group"><label>…</label><select>
  with <label> directly wrapping <select> (implicit association,
  removes .search-filter-group divs); CSS updated to display:flex on
  the label itself
- Pagination wrapper changed to <nav aria-label="Pagination">;
  page-info span gets aria-current="page"
- search.css: delete .search-results-view, four index-item classes,
  .cat-index-group, .search-filter-group; consolidate years/other
  column link styles under .repertoire-col:first-child ul a and
  .repertoire-col:not(:first-child) ul a selectors; add ul reset rule

+- [x] **`<div class="results-grid">`** is a list of search results. Replace with `<ul class="results-grid">`.
       Each `<a class="result-card">` becomes a `<li><a>` - the link text is made up of child `<span>`s
       which is correct. However `.result-card__authors` and `.result-card__title` `<span>`s would be
       better as `<strong>` (author, emphasis) and the title as plain text or `<span>`. The year/meta
       `<span class="result-card__meta">` → `<small>` (ancillary metadata).

       four children are semantic candidates: each `.repertoire-col` is an independent index with a
       heading. Replace `<div class="repertoire-col">` with `<section>`. The heading
       (`<h2 class="repertoire-col__header">`) is already correct - `<h2>` is right. Remove
       `.repertoire-col__header`; CSS targets `section > h2` scoped inside `.repertoire-index`.

+- [x] **`.year-index-item`, `.cat-index-item`, `.student-index-item`, `.keyword-index-item`** - all
       four are sequences of `<a>` links with `display:block`. They are lists. Wrap each group in
       `<ul>`; each link becomes `<li><a>`. The four custom classes collapse to a single `ul a`
       selector per column (or no class at all, scoped via `section`). The `.active` class on links
       → `aria-current="page"` on the `<a>`.

       a plain `<p>` styled with `.search-main p:first-child` or just keep a lightweight class. Or use
       `<output>` since it is a computed result count.
