Suggestion: add UI toggle for `default_impl` attribute in contract generation

[jsmaxi]

Currently, the OpenZeppelin Wizard for Stellar (https://wizard.openzeppelin.com/stellar) generates contracts that use default_impl attribute to implement all trait functions, when possible.

Suggestion is to add a UI toggle to choose between:

• Using the #[default_impl] attribute (could be the default option)
• Generating explicit implementations of all trait functions

Example for Fungible Token: https://github.com/OpenZeppelin/stellar-contracts/blob/a5fada3912bc4744eea81db97ad3a0f8adda6099/examples/fungible-capped/src/contract.rs#L32

Hi @jsmaxi thanks for reporting the issue, could you explain more your use case and the added benefit of adding the explicit implementation of all trait function?

@CoveMB Thanks for checking.

This would be primarily for convenience to accommodate various user needs. I envision two main use cases:

• Some users may want to inspect all available trait functions directly in the wizard UI to understand what's possible without diving into documentation or source code.

• Others may want to override specific trait functions with custom behavior.

That said, I understand this could be a significant implementation effort. If you think the benefit doesn't justify the work involved, or this is not reasonable, I'm happy to close this issue or discuss alternatives.
