fix(wallet): Remove Debug formatting from Display implementation #1868

[rajanarahul93]

Description

This PR removes the Debug formatting from the Display implementation for LoadError in crates/wallet/src/wallet/mod.rs.
Instead of using {:?} (which invokes Debug formatting), we now use {} to provide a more user-friendly error message.
This change improves readability and aligns with best practices for Display implementations.

Notes to the reviewers

• The LoadError::Mismatch message was updated to explicitly state "expected X, but found Y", making it clearer.
• The LoadError::MissingDescriptor message now displays the keychain value using {} instead of {:?}, ensuring a more user-friendly output.

Changelog notice

• Fixed: Removed Debug formatting from Display implementation in LoadError for better readability.
