fix(idb-sort): correct tmp_sort_* comparator direction in journals, IDAA recovery meetings, and BB post comments

build_tmp_sort() encodes priority=true as '0' for ascending sort. JS comparators
were using b.localeCompare(a) (descending), inverting the encoding so priority=false
items sorted first. Fixed to a.localeCompare(b) in ae_journals_search_helpers.ts (3
sites in recovery_meetings +page.svelte and wrapper component).

Also fixes a Dexie anti-pattern in bb/[post_id]: .reverse() before .sortBy() is a
no-op in Dexie; moved array .reverse() to after the await.

Documents the encoding rule and legacy inverted-encoding modules in
GUIDE__SvelteKit2_Svelte5_DexieJS.md and adds mistake #15 to BOOTSTRAP quickstart.

+15. **`tmp_sort_*` comparators written descending instead of ascending** — `build_tmp_sort()` encodes `priority=true` as `'0'` and `priority=false` as `'1'`, designed for **ascending** sort so priority items appear first. Writing a JS `.sort()` comparator as `b.localeCompare(a)` (descending) inverts the encoding and sends priority items to the bottom.

+    ```ts
+    // ❌ Wrong — descending puts priority=false ('1') before priority=true ('0')
+    list.sort((a, b) => (b.tmp_sort_1 ?? '').localeCompare(a.tmp_sort_1 ?? ''));
+
+    // ✅ Correct — ascending matches build_tmp_sort encoding
+    list.sort((a, b) => (a.tmp_sort_1 ?? '').localeCompare(b.tmp_sort_1 ?? ''));
+    ```
+
+    **Companion Dexie trap:** `collection.reverse().sortBy('tmp_sort_*')` — Dexie ignores a collection-level `.reverse()` when `.sortBy()` is called. The sort is always ascending. To reverse the result, call `.reverse()` on the returned array after `await`. See `GUIDE__SvelteKit2_Svelte5_DexieJS.md` → `build_tmp_sort` section.
