Improved Navigation and Sign-In Experience

Enhanced app navigation with a new top navigation stack, conditional profile visibility for signed-in users, and added sign-out functionality. Updated input fields and modal interactions improve usability.

What's New

• Introduced a top-level navigation stack including Home, Settings, and Filters screens for smoother navigation.

• Profile button in the header is now visible only when users are signed in, reducing clutter for signed-out users.

• Added a 'Terminar sessão' button in Settings allowing users to sign out easily.

• When signed out, the Statistics screen and profile access are hidden to match user authentication state.

Improvements

• Login form input updated to disable autocorrect and set proper email input mode for better typing accuracy.

• Input fields now show focused state with a distinct border color to improve field visibility.

• Modal close control refined for clearer interaction with an improved pressable area.

• Bottom tab bar height and item margin have been adjusted for consistent appearance across platforms.
