feat: use serde_path_to_error

[joe-p]

Leverages path_to_error to get better serde error messages

Example from an algod serialization error:

Before:

"Serialization error: string found to be invalid utf8: invalid utf-8 sequence of 1 bytes from index 0"

After:

"Serialization error: block.txns[10].dt.gd.current_miner.bs: string found to be invalid utf8: invalid utf-8 sequence of 1 bytes from index 0"

Pull request overview

This PR enhances error reporting across the Algorand SDK by integrating the serde_path_to_error library. When deserialization fails, error messages now include the full path to the problematic field (e.g., block.txns[10].dt.gd.current_miner.bs), making debugging significantly easier compared to generic error messages.

Key Changes:

• Added serde_path_to_error dependency to all client crates and core libraries
• Replaced direct serde_json::from_slice and rmp_serde::from_slice calls with serde_path_to_error::deserialize throughout the codebase
• Updated code generation templates to emit the new deserialization pattern for future API changes
• Added new error variant DecodingErrorWithPath in algokit_transact to preserve path information
