## Polkadot upgrade 2503
In this PR, we upgrade form Polkadot SDK 2412 to Polkadot SDK 2503. In
order to upgrade the SDK we need to upgrade some dependencies :
StorageHub and frontier simultaneously.
## What changes
### Trivial changes
* https://github.com/paritytech/polkadot-sdk/pull/7634 -> The new trait
is required in all the pallets using scale encoding.
* https://github.com/paritytech/polkadot-sdk/pull/7043 -> Remove
deprecated `sp-std` and replace with `alloc` or `core`.
* https://github.com/paritytech/polkadot-sdk/pull/6140 -> Accurate
weight reclaim with frame_system::WeightReclaim
### Breaking changes
* https://github.com/paritytech/polkadot-sdk/pull/2072 -> There is a
change in `pallet-referenda`. Now, the tracks are retrieved as a list of
`Track`s. Also, the names of the tracks might have some trailing null
values (`\0`). This means display representation of the tracks' names
must be sanitized.
* https://github.com/paritytech/polkadot-sdk/pull/5723 -> adds the
ability for these pallets to specify their source of the block number.
This is useful when these pallets are migrated from the relay chain to a
parachain and vice versa. (Not entirely sure it is breaking as it is
being marked as backward compatible).
* https://github.com/paritytech/polkadot-sdk/pull/6338 -> Update
Referenda to Support Block Number Provider
### Notable changes
* https://github.com/paritytech/polkadot-sdk/pull/5703 -> Not changes
required in the codebase but impact fastSync mode. Should improve
testing.
* https://github.com/paritytech/polkadot-sdk/pull/5842 -> Removes
`libp2p` types in authority-discovery, and replace them with network
backend agnostic types from `sc-network-types`. The `sc-network`
interface is therefore updated accordingly.
## What changes in Frontier
* https://github.com/polkadot-evm/frontier/pull/1693 -> Add support for
EIP 7702 which has been enable with Pectra. This EIP add a new field
`AuthorizationList` in Ethereum transaction.
Changes example :
```rust
#[test]
fn validate_transaction_fails_on_filtered_call() {
...
pallet_evm::Call::<Runtime>::call {
source: H160::default(),
target: H160::default(),
input: Vec::new(),
value: sp_core::U256::zero(),
gas_limit: 21000,
max_fee_per_gas: sp_core::U256::zero(),
max_priority_fee_per_gas: Some(sp_core::U256::zero()),
nonce: None,
access_list: Vec::new(),
authorization_list: Vec::new(),
}
.into(),
```
## ⚠️ Breaking Changes ⚠️
* Upgrade to Stirage hub v0.5.1
* Support for Ethereum latest upgrade (txs now have the
`authoriation_list` for support EIP 7702)

## 🔨 Add Slashing Support for Runtime
This PR introduces the slashing functionality for the DataHaven runtime,
enabling punitive measures against misbehaving validators.
### Features
- Deferred slashing with configurable veto periods
- Cross-chain slashing message delivery trough Snowbridge
- Governance controls for slashing parameters and emergency cancellation
We introduced the `external-validator-slashes` pallet, which allows to
slash validators that misbehave. The slashing is triggered when an
offence is reported via the offence pallet (which is already
implemented). The message is sent through Snowbrige's outbound queue and
the real slashing happens in the contracts side, which will come in a
follow up PR.
There is a configurable window of time between the time the validator is
being reported, and the time the slash is triggered. This allows that in
case of an error we are still able to cancel the slashing, using a sudo
account.
For convenience, we also have extrinsics for corner cases:
- **`force_inject_slash`**: Root-only function to manually inject
slashes for specific validators with custom percentages. Useful for
emergency situations or governance-directed slashing outside normal
offence detection
- **`cancel_deferred_slash`**: Allows governance to cancel pending
slashes during the defer period by specifying era and slash indices.
Provides safety mechanism against false positives or malicious slash
reports
- **`set_slashing_mode`**: Configurable slashing behavior with three
modes - `Enabled` (normal operation), `LogOnly` (track offences without
applying slashes), and `Disabled` (completely halt slashing). Critical
for emergency response and testing

This PR replaces `pallet-validator-set` with a new
`pallet-external-validators` pallet from Tanssi.
## Key Changes
- **New ExternalValidators Pallet**
- Supports whitelisted validators (set by governance, not rewarded)
- Manages external validators (can be enabled/disabled)
- Implements era-based rotation (eras change after configurable
sessions)
- **Bridge Integration**
- Updated `EigenLayerMessageProcessor` in
`operator/primitives/bridge/src/lib.rs`
- Replaced the old `SetValidators` command with
```rust
ReceiveValidators { validators, external_index }
```
