The v3 Songs filter/search bar (added by #857) is `sticky top-0 z-20 backdrop-blur`
— the SAME z-index and stacking-context recipe as the global topbar, and being
later in source order it won the z-20 tie and painted over the topbar's whole
subtree. So the topbar's instrument-selector dropdown (`data-inst-menu`, z-50
*within* the topbar's z-20 context) rendered BEHIND the filter bar.
Bump the topbar to z-30 so it (and its dropdowns) stack above the per-screen
filter bar. `.z-30` is already in the prebuilt tailwind.min.css, so no rebuild.
Reproduced + verified headless: in the filter-bar/menu overlap region the
topmost element flips from the filter bar's <select> to the instrument menu.
(The tuner panel #tuner-plugin-ui is z-[1000] on document.body and was already
on top — unaffected.)

(cherry picked from commit 45bfd9cc9c6981a10a9f2441638b7e5bee760dc8)
- diagnostics_redact: keep '.psarc' in the song-filename scrub regex.
The purge swapped it for '.archive' (not a real extension), which
would leak real .psarc filenames still on users' disks into
diagnostic bundles. This is a redaction allow-list, not brand text.
- sloppak: the legacy lyrics-source alias was a no-op
({"notechart": "notechart"}), so old manifests with
lyrics_source=="sng" fell back to "xml" instead of migrating.
Map {"sng": "notechart"} so the rename stays back-compatible.
