fix(privacy): sanitize console error/warn to prevent PII leakage

Replace raw error object logging (which may contain Matrix event
payloads, user IDs, or message bodies) with e.message-only strings
in three files:
- CallEmbed.ts: state update and event widget feed errors
- msgContent.ts: image/video element load failures and thumb errors
- RoomInput.tsx: GIF send failure

 ## 🚩 Critical & UI Bugs
 
+### 12. PiP Mute Icon Misidentifies Whose Mic Is Muted
+
+- **File:** `cinny/src/app/components/CallEmbedProvider.tsx`
+- **Status:** **FIXED ⚠️ UNTESTED** — needs verification in a live call with at least one other participant who mutes/unmutes
+- **Issue:** The muted-mic badge in the Picture-in-Picture window used `useRemoteAllMuted` (fires when ANY remote participant is muted) and rendered in the bottom-left corner — the conventional position for "YOUR" mic status. Users read it as their own mic being muted.
+- **Root Cause:** `PipMuteOverlay` was triggering on remote-mute events while displaying in a position that implies local-user status.
+- **Fix Applied:**
+  - **Bottom-left badge** now shows only when the LOCAL user's mic is muted (checked via `!controlState.microphone` from `useCallControlState`). Includes "You" label to make it unambiguous. Uses `color.Critical.Main`.
+  - **Top-right badge** (new) shows "All muted" in `color.Warning.Main` when all remote participants are muted — positioned and labeled so it's clearly about other people, not the local user.
+  - Both badges use `aria-label` / `title` for accessibility.
