Exposed transaction version numbers are now treated as unsigned 16-bit integers
instead of signed 16-bit integers. This matches their treatment in consensus
logic. Versions greater than 3 continue to be non-standard (matching previous
behavior of smaller than 1 or greater than 3 being non-standard). Note that
this includes the joinpsbt command, which combines partially-signed
transactions by selecting the highest version number.

Docker Build System

Modified the Dockerfile to exclude the `dash-qt` graphical wallet interface from the set of binaries copied to
`/usr/local/bin` during the Docker image build process. This change streamlines the Docker image, making it more
suitable for server environments and headless applications, where the graphical user interface of `dash-qt` is not
required. The update enhances the Docker image's efficiency by reducing its size and minimizing unnecessary components.

- `getassetunlockstatuses` RPC allows fetching of Asset Unlock txs by their withdrawal index.
The RPC accepts an array of indexes and an optional block height.
The possible outcomes per each index are:
- `chainlocked`: If the Asset Unlock index is mined on a ChainLocked block or up to the given block height.
- `mined`: If no ChainLock information is available for the mined Asset Unlock index.
- `mempooled`: If the Asset Unlock index is in the mempool.
- `unknown`: If none of the above are valid.
Note: If a specific block height is passed on request, then only `chainlocked` and `unknown` outcomes are possible.

RPC Changes
-----------
### `submitchainlock` RPC method updates
- **Return Value Addition**: The method now returns the height of the current best ChainLock, allowing clients to easily compare the provided ChainLock height with the current best one.
- **Error Handling**: Added a check for the provided block height. If the block height is not greater than the height of the current best ChainLock, the method will return the best ChainLock's height without attempting to process a new ChainLock.
- **Code Optimization**: Refactored the retrieval of the `LLMQContext` and the best ChainLock's height to occur before the signature validation. This change streamlines the logic and potentially reduces redundant computations when the provided block height is already known to be not the best.

# Notable changes
## HD Wallets Enabled by Default
In this release, we are taking a significant step towards enhancing the Dash wallet's usability by enabling Hierarchical Deterministic (HD) wallets by default. This change aligns the behavior of `dashd` and `dash-qt` with the previously optional `-usehd=1` flag, making HD wallets the standard for all users.
While HD wallets are now enabled by default to improve user experience, Dash Core still allows for the creation of non-HD wallets by using the `-usehd=0` flag. However, users should be aware that this option is intended for legacy support and will be removed in future releases. Importantly, even with an HD wallet, users can still import non-HD private keys, ensuring flexibility in managing their funds.

Updated RPCs
------------
- The `testmempoolaccept` RPC returns `vsize` and a `fee` object with the `base` fee
if the transaction passes validation.
- The `testmempoolaccept` RPC now accepts multiple transactions (still experimental at the moment,
API may be unstable). This is intended for testing transaction packages with dependency
relationships; it is not recommended for batch-validating independent transactions. In addition to
mempool policy, package policies apply: the list cannot contain more than 25 transactions or have a
total size exceeding 101K virtual bytes, and cannot conflict with (spend the same inputs as) each other or
the mempool. There are some known limitations to the accuracy of the test accept: it's possible for
`testmempoolaccept` to return "allowed"=True for a group of transactions, but "too-long-mempool-chain"
if they are actually submitted.

## Asset lock and unlock transactions Legacy InstantSend was deprecated with the activation of Deterministic InstantSend, but we kept the underlying logic for some time to ensure a smooth transition. v20.1 finally removes all Legacy InstantSend logic and will no longer support sending and receiving islock p2p messages and inv p2p messages with id 30.
