HoneyandClaude Opus 4.8 26880016e9 feat(scrobble): web statistics view (Phase 3 UI)
Opens from Settings ("Meine Statistiken") as a self-contained modal overlay
(no router changes). Fetches GET /scrobble/stats and renders: totals tiles
(plays + listening time), a per-bucket play series, top artists/tracks/albums
with mini bars, and a 24h listening clock. Period tabs (all / this year /
last 30 days) switch from/to + bucket. Vanilla inline SVG-free bars, no chart
lib. Reuses .modal-overlay.open + design tokens; sends local tz offset for
day bucketing. Graceful empty/error/unconfigured states. SW cache -> ns-v65.
