Subject: [PATCH] fix(ui): faster bitcoin sync refresh + unstick ElectrumX
 loader (B15,B7)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

B15: Home system stats (incl. bitcoin sync %) polled every 30s — too slow;
now 10s so sync progress tracks the actual block height more closely.

B7: the ElectrumX sync overlay was gated only on status!=='synced', so if
the status never flips to 'synced' (ElectrumX stale/disconnected) the loader
stuck on top forever. Now the overlay hides and the app iframe loads when
the sync status is stale (fail-open), while still showing during active
indexing. type-check EXIT 0.

 ### B13 — Fedimint UI not applying CSS — TODO
 Actual Fedimint UI (not pre-sync) renders unstyled. Likely asset path / proxy base-href (assets rooted at `/` vs `/app/fedimint/`). PROGRESS: nginx /app/fedimint/ proxies to :8175 with sub_filter for nostr-provider but NO base-href/asset rewrite. Fedimint UI head has no static CSS link in first 1.2KB (likely JS-module-loaded assets rooted at /). NEXT: dump full fedimint HTML + check if assets request /assets/* (which hit the SPA, not :8175). Fix = inject <base href="/app/fedimint/"> via sub_filter OR rebuild app with correct base. Needs deeper per-app look (fresh context ok).

+### B15 — Bitcoin UI sync progress lags — FIXED (Home.vue poll 30s→10s). UI-confirm.
 Bitcoin UI doesn't update its sync progress fast enough even though the console clearly already has the block-height data. Likely a polling-interval / reactive-update gap between the status source and the UI.

+### B16 — Bitcoin sync status vanishes — DEFERRED (homeStatus.ts already partly retains last value; safe fix needs UI test to avoid showing stale-as-live; plan in findings)
 The bitcoin sync status in the Home > System container disappears when it should persist/cache and show an "updating" state. Related to B15 (Bitcoin UI sync lag). Likely the status component clears on empty/transitional poll instead of retaining last-known + showing updating.
