Supabase Login Fix & One-Time Tasks Feature to next.js app

Hi,

im looking fo a developer or team to help me with a few things in my customer scheduling and routing application. Here is what i need completed.

Current Issues:
1. Login Functionality
- Users are experiencing "AuthRetryableFetchError: NetworkError" when attempting to sign in
- The error occurs in the SignInForm component during the signInWithPassword call
- Current Supabase configuration:
- Project URL: https://hpyiacedlukfebyzaawp.supabase.com
- Using Next.js 15.1.7 with Turbopack
- Environment variables are properly set in .env file

2. Database Structure
- The app uses Supabase with several tables:
- businesses
- crews
- customers
- optimized_routes
- completed_jobs
- one_time_jobs

Required Fixes:
1. Login System

- Implement proper error handling and user feedback
- Ensure session persistence works correctly
- Add proper loading states during authentication

New Feature Requirements:
1. One-Time Task System
