Create rewards/earnings contract stub

[aji70]

Description

The goal is to create a contract to track and withdraw creator earnings. Create contracts/creator-earnings/ with initialize(env, admin, token_address), deposit(env, creator, amount) (callable by subscription/content contracts), balance(env, creator) -> i128, withdraw(env, creator, amount) (creator authorizes). Add unit tests for deposit, balance, withdraw, and insufficient balance revert.

Tasks

1. Implement initialize:

   • Store admin and token address

2. Implement deposit:

   • Callable by authorized contracts (or admin)
   • Add amount to creator balance
   • Or: transfer tokens to contract and credit creator

3. Implement balance:

   • Return creator's balance

4. Implement withdraw:

   • Creator authorizes
   • Transfer tokens from contract to creator
   • Decrease balance
   • Revert if insufficient balance

5. Add tests:

   • Deposit increases balance
   • Withdraw decreases balance and transfers tokens
   • Insufficient balance revert

Additional Requirements

• Consider authorization: only subscription/content contracts can deposit

Acceptance Criteria

• Earnings can be deposited
• Creators can withdraw
• Balance accurate
• All tests pass
