Launchpad MVP iteration and fix

[MSghais]

Description

• [ ] Clean code and refactoring
• [ ] Verify all assert
• [ ] Verify bonding curve formula
• [ ] Check amount received in tests:

80% of the total supply 20% go to liquidity with the threshold

Tests issues:

• [ ] Fix end_to_end tests
• [ ] BOUNDS_OUT_OF_RANGE
• [ ] Suboverflow own Unrug liq
• [ ] Test Liquidity Unrug with Bonding curve
• [ ] - Test Unrug liquidity LP (without the launch bonding curve)
• [ ] - when uncomment add_liquidity_ekubo in the buy_coin, we have a very strange issue like CORE_ONLY() when contract call it directly after threshold reached, that not do the same when we call the public one

May I take this issue on?

Hi! @MSghais I'm Joseph Poveda, I'm a member of the Dojo Coding community. A bit about my background is that I'm just starting out with Only Dust and I want to contribute as much as I can to the project. My knowledge of different programming languages ​​will allow me to better solve problems. To solve this issue I will:

1. Clean Code and Refactoring:
   • Review the codebase and refactor for clarity and efficiency.
   • Ensure all assert statements are verified and correctly implemented.
2. Verify Bonding Curve Formula:
   • Check the bonding curve formula for accuracy.
   • Ensure the calculations for the amount received in tests are correct (80% of the total supply, 20% to liquidity with the threshold).
3. Fix End-to-End Tests:
   • Address issues causing BOUNDS_OUT_OF_RANGE and Suboverflow own Unrug liq.
   • Test liquidity unrug with and without the bonding curve.
4. Investigate and Fix Specific Issues:
   • Debug the issue with add_liquidity_ekuboin the buy_coin function.
   • Resolve the CORE_ONLY() issue when the contract calls it directly after the threshold is reached.
5. Run and Verify Tests:
   • Ensure all tests pass and verify that the changes do not introduce new issues.
