Merge Sarah Login Screen Updates into Main

[gbojo]

1. Updated src/pages/Login.tsx to apply the new dark green gradient:

          start={{ x: 0.0, y: 0.6 }}
          end={{ x: 0.0, y: 1.0 }}
          colors={['#0e422aff', '#1e2b202c']}
   

   • Removed the mismatched locations prop that caused Expo warnings.
   • Adjusted layout spacing and improved readability on the login form.
   • Verified app build and visual consistency on Android emulator.

2. Differences Between Branches (via Diff Tool):

   • Main lacked the dark-green gradient updates.
   • Sarah-login-screen-initial includes all login UI refinements and merged José’s gradient corrections.
   • Only Login.tsx was modified; no files were added or deleted.

3. Conflict Resolution

   • Sarah's branch was cloned and updated by Jose.
   • No merge conflicts occurred between the branches because Sarah's branch was behind Jose's.
   • All potential differences were resolved earlier during the José → Sarah merge, resulting in a fast-forward update.
