feat(monad): Add Monad testnet

[satoshiotomakan]

This pull request adds support for the Monad Testnet (MON) blockchain across the codebase. The changes include updates to registry files, coin type enumerations, address derivation tests, and documentation to fully integrate Monad as a supported chain.

Monad Testnet integration

• Added Monad Testnet entry to registry.json, including metadata such as coin ID, symbol, derivation path, explorer URLs, and RPC/documentation links.
• Registered Monad Testnet in the coin type enumeration (TWCoinTypeMonad = 10143) in TWCoinType.h.
• Added Monad Testnet to the documentation table in docs/registry.md.

Address derivation and tests

• Updated address derivation tests in Kotlin, Android, Swift, Rust, and C++ to include Monad Testnet, ensuring correct address formats are validated. [1] [2] [3] [4] [5]
• Added a dedicated C++ test file TWCoinTypeTests.cpp for Monad, verifying symbol, ID, name, decimals, blockchain type, and explorer/account URLs.
