Add Fuzz Testing for Bridge Receiver Contract

[EDOHWARES]

Description

Fuzz testing is crucial for ensuring our smart contracts behave predictably under extreme and randomized conditions. Currently, the Bridge Receiver contract lacks a fuzzing suite.

Steps to Complete

1. Use a fuzzing library like proptest in Rust.
2. Add a proptest! block inside the Bridge Receiver test files.
3. Generate randomized valid and invalid inputs for the core state-changing functions.
4. Ensure the contract panics gracefully or returns expected errors instead of corrupting state.
5. Ensure cargo test passes successfully.
