Server may be reachable even if ping failed (transient timeout).
User should always be able to try connecting. Fingerprint change
still shows confirm dialog (accept/reject).

Identicon generator:
- Deterministic 5x5 symmetric pattern from fingerprint hash
- HSL-derived colors, rendered as inline SVG
- Click any identicon to copy its fingerprint to clipboard
- Used for participants, user identity, and relay servers
Server identity (TOFU — Trust On First Use):
- Ping returns server fingerprint (QUIC peer certificate hash)
- First contact: auto-saved as known fingerprint
- Subsequent pings: compared against known fingerprint
- Lock icons: locked (verified), unlocked (new), warning (changed), red (offline)
- Fingerprint mismatch shows confirmation dialog before connecting
UI updates:
- Participants show identicons instead of letter avatars
- User identity shows identicon + fingerprint on connect screen
- Manage Relays shows identicon per server with lock status
- Relay button shows lock icon instead of colored dot

- Click relay button opens Manage Relays dialog directly (no dropdown)
- Click a relay in the dialog to select it (highlighted with accent border)
- × button to delete, Add Relay button to add new
- Removed all dropdown menu code and CSS

- Dialog fits within 360px window (was overflowing at 420px)
- Add inputs stacked: name + host:port in a row, "Add Relay" button below
- Text overflow with ellipsis on relay names and addresses
- Proper min-width: 0 on flex children to prevent overflow

- Relay selector as dropdown with green/yellow/red status dots
(green < 200ms, yellow > 200ms, red = offline, gray = unknown)
- All relays pinged on startup, RTT shown next to each
- "Manage Relays..." dialog: add/remove servers, see live status
- Clicking a relay in dropdown selects it, fills connect form
- Recent room chips auto-select matching relay
- Migrates old single-relay settings format automatically
- Prevents connecting to offline relays

- New ping_relay Tauri command: QUIC connect with 3s timeout, returns RTT ms
- Relay status shown next to input field: "42ms" (green) or "offline" (red)
- Auto-pings on app startup and debounced on relay input change
- Fix SyncWrapper dead_code warning with #[allow(dead_code)]

#7 Fingerprint shown before connecting — new get_identity command reads
~/.wzp/identity at startup (generates if missing). Click to copy.
#8 Recent rooms store (relay, room) pairs — clicking a chip fills both
fields. Settings panel shows relay alongside room name. Migrates
old string[] format automatically.
#9 Auto-reconnect on unexpected disconnect — exponential backoff
(1s, 2s, 4s... max 10s), up to 5 attempts. Yellow blinking dot
shows reconnecting state. Stops if user clicks hangup.
#10 Audio handle cleanup — CPAL handles stored in SyncWrapper (no more
mem::forget), dropped properly on CallEngine::stop().

The VPIO/CPAL audio handles were dropped at the end of start(),
killing the audio unit immediately. Audio I/O stopped working
after the first frame.
- Store audio handle in CallEngine via SyncWrapper
- Drop MutexGuard before returning from status() (Send future)
- Audio streams now live for the entire call duration

- Change status() from blocking_lock to async lock().await —
fixes "Cannot block the current thread from within a runtime" panic
that froze the call timer and broke audio
- Click fingerprint to copy to clipboard (both connect and settings screens)
- Show "Copied!" feedback on click

send_datagram() returns Err(Blocked) when the QUIC congestion window
is full. This is transient — the window reopens once ACKs arrive.
Previously, all send paths treated this as fatal (break/return),
which killed the send task and cascaded via tokio::select! to kill
the entire call.
Now: log warning, drop the packet, continue. Brief audio glitch
(20-100ms) instead of complete call death. FEC on the receiver
side recovers most dropped packets.
Fixed in:
- CLI run_live send task (continue + error counter)
- CLI run_file_mode send paths (2 locations)
- Desktop engine send task
Also hardened recv tasks: transient errors (non-closed/reset)
are survived instead of causing exit.
Matches the fix applied to Android client (engine.rs).
