Add Multiplayer preview to unauthenticated Settings

[anamhira47]

Summary

Adds a Multiplayer section to the unauthenticated Settings screen so signed-out users can see how crew-based multiplayer works before logging in.

In SweepAlert, multiplayer is the car crew experience: shared cars, move claims, crew alerts, and invite links for roommates/partners.

What changed

• Replaced the locked "Crew" placeholder on signed-out Settings with a full Multiplayer preview card
• Shows demo crew data (Apartment car crew, 3 players, 2 cars) from SharedCarCrew.demo
• Highlights three multiplayer features: shared alerts, claim moves, invite links
• Adds a dedicated Log in to start multiplayer CTA (multiplayer-login-button)

Before

Map screen (signed-out state before opening Settings):

Previously, signed-out Settings only showed a locked Crew row: "Sign in to manage cars."

After

Settings → Multiplayer section (verified on Revyl device):

Device verification

• Remote build succeeded (revyl build --remote --platform ios)
• App reinstalled on Revyl simulator and opened to Settings (unauthenticated)
• Verified visually: MULTIPLAYER section shows preview crew, 3 player avatars (L/A/M), feature bullets, and Log in to start multiplayer button

Files changed

• apps/ios-sweep-alert/SweepAlertSwift/ContentView.swift — signedOutMultiplayerSection replaces signedOutCrewSection

What we exercised

We launched the app in a signed-out state and opened the Settings panel. Under Settings, we verified that the old locked crew placeholder is replaced by the new Multiplayer preview card. This card successfully displays the demo crew name, member avatars, cars, and the login call-to-action button, ensuring signed-out users get a clear preview of the multiplayer feature.
