[Profile] Add guest profile sign-in flow

[conniecliu]

Overview

This implements the skip sign-in flow for when a user skips the sign-in prompt. Changes include:

• New guest profile screen that appears when a user is not logged in.
• Replaced main logo PNG with XML for visual clarity.
• Modified buttons and navigation for new flow and UI.

Details on the flow and UI can be found in this Figma.

Changes Made

• Added a GuestProfileScreen that appears only if the user skipped the sign-in prompt during early onboarding.
• Modified existing buttons to accommodate the new UI for the GuestProfileScreen
• Replaced the main logo with an XML instead of a PNG.
• Added a new XML file for the goals logo specifically for the guest profile.
• Modified MainNavigationWrapper and RootNavigationViewModel to prevent the user from backing back into the onboarding flow after onboarding is completed + direct them to login if they haven't already + be directed to Home.

Test Coverage

• Tested on my Google Pixel 9a.

Layer / File(s)	Summary
Guest profile UI and sign-in entry app/src/main/java/com/cornellappdev/uplift/ui/screens/profile/GuestProfileScreen.kt, app/src/main/java/com/cornellappdev/uplift/ui/components/onboarding/auth/LogInButton.kt, app/src/main/java/com/cornellappdev/uplift/ui/components/general/UpliftButton.kt, app/src/main/res/drawable/*	Adds the guest profile layout, benefit rows, logo, goal icon, and Google sign-in callback. LogInButton accepts and applies a Modifier. UpliftButton uses a fresh modifier for its text.
Session-derived navigation state app/src/main/java/com/cornellappdev/uplift/ui/viewmodels/nav/RootNavigationViewModel.kt	Adds withSession to update session state and emit navigation events when the route or login state changes.
Profile route and back-stack navigation app/src/main/java/com/cornellappdev/uplift/ui/MainNavigationWrapper.kt	Renders GuestProfileScreen for logged-out users. Home navigation uses popUpTo(0) and launchSingleTop = true.
