Subject: [PATCH] repertoire: HTMX OOB swaps for filter columns + fix fading
 edge cases

Switch from swapping the entire #repertoire-index block to targeted
hx-swap-oob swaps: only the <ul> list elements are replaced, while
section headers and accordion chrome stay in the DOM untouched.

- Filter column <ul>s get IDs (rep-list-years, rep-list-ap, etc.)
  and render with hx-swap-oob=true on HTMX requests
- Students <ul> gets id=rep-students as main swap target
- Filter buttons now target #rep-students instead of #repertoire-index
- Server sets $isOob=true when rendering HTMX partial responses
- Accordion re-init on swap no longer needed (headers never replaced)
- Scroll-restore updated to capture/restore per <ul> ID

Fading fixes:
- Restore rep-entry--faded class with simplified logic: any active
  filter fades entries whose matched flag is false (removed the
  $colHasMatch gate that prevented fading when a column had no matches)
- Add $noResults guard: when matched_ids is empty, force-fade all
  non-selected entries across ALL columns
- Fix keyword matched computation: use full intersection
  ($buildWhere('__none__')) instead of excluding the keyword filter.
  Previously keywords were matched against only non-keyword filters,
  so selecting a keyword would not narrow the available keyword set,
  causing entries to appear valid that would yield zero results.
