feat: ✨ Update chain IDs & native token tickers for all 3 environments (#280) 
Update the 3 DataHaven environments' chain IDs & native token ticker as
follows:

* **Mainnet**
  * **Chain ID**: 55930
  * **Ticker**: HAVE
* **TestNet**
  * **Chain ID**: 55931
  * **Ticker**: MOCK
* **Stagenet**
  * **Chain ID**: 55932
  * **Ticker**: STAGE

The PR includes a storage migration for the Stagenet & Testnet
environments, that are already live, to update the EVM Chain ID stored
in the `pallet-evm-chain-id` pallet.

Note: the token symbol will only be updated with the genesis config
presets or newly generated chain specs. For already live networks, the
existing chain spec must be updated (i.e. the tokenSymbol property
changed) and used by all nodes in the network. This change in the chain
spec will not alter the chain genesis so it safe to do (in the very
early stages of the chain obviously).

feat: ✨ Standardize currency system to HAVE token with Wei-based units (#130) 
## Summary

This PR modernizes DataHaven's currency system by standardizing all
three runtimes (mainnet, stagenet, testnet) to use Ethereum-compatible
Wei-based units with HAVE as the native token name.

### Key Changes

#### 🔄 Currency Unit Standardization
- **Migrated from decimal-based to Wei-based system** (18 decimals)
- **Wei units**: WEI → KILOWEI → MEGAWEI → GIGAWEI 
- **HAVE units**: MICROHAVE → MILLIHAVE → HAVE → KILOHAVE
- **Zero Existential Deposit**: Enables dust account support with
`insecure_zero_ed` feature

#### 🏷️ Token Naming
- **UNIT → HAVE**: Native token renamed to reflect DataHaven branding
- **Consistent terminology**: All constants, comments, and documentation
updated
- **Supply factors preserved**: Mainnet (100x), Stagenet/Testnet (1x)

#### ⚖️ Block Weights & Gas Configuration
- **Solochain-optimized**: Updated MAX_POV_SIZE and block weight
parameters
- **EVM compatibility**: Fixed GasLimitPovSizeRatio (u32 → u64) and
storage growth ratios
- **Proper fee structure**: Aligned with Ethereum standards

#### 🧪 Test Updates
- **Treasury tests fixed**: Updated to handle zero existential deposit
behavior
- **All tests passing**: Currency references updated across all runtime
tests
- **Storage hub parameters**: Updated to use HAVE token terminology

### Breaking Changes

⚠️ **Currency precision changed from 12 to 18 decimals**
- Applications using currency constants must update to new HAVE-based
naming
- ExistentialDeposit now 0 (was previously enforced minimum balance)

### Runtime Coverage

- ✅ **Mainnet runtime** (supply factor: 100)
- ✅ **Stagenet runtime** (supply factor: 1)  
- ✅ **Testnet runtime** (supply factor: 1)
- ✅ **Storage hub parameters** (runtime params updated)

### Technical Details

#### Fee Structure
```rust
pub const TRANSACTION_BYTE_FEE: Balance = 1 * GIGAWEI * SUPPLY_FACTOR;
pub const STORAGE_BYTE_FEE: Balance = 100 * MICROHAVE * SUPPLY_FACTOR;
pub const WEIGHT_FEE: Balance = 50 * KILOWEI * SUPPLY_FACTOR / 4;
```

#### Block Configuration
```rust
pub const MAXIMUM_BLOCK_WEIGHT: Weight = Weight::from_parts(
    WEIGHT_REF_TIME_PER_SECOND.saturating_mul(2),
    MAX_POV_SIZE as u64,
);
```

## Test Plan

- [x] All runtime builds compile successfully
- [x] All unit tests pass across three runtimes
- [x] Treasury fee handling verified with zero existential deposit
- [x] Storage hub parameter compatibility confirmed
- [x] EVM gas limit calculations validated

## Files Modified

**27 files changed, 728 insertions(+), 342 deletions(-)**

- Runtime lib.rs files (currency module definitions)
- Cargo.toml files (insecure_zero_ed feature)
- Configuration modules (block weights, gas limits)
- Test suites (currency constant references)
- Storage hub runtime parameters

## Summary by CodeRabbit

- New Features
- Introduced a unified currency module with HAVE units (18 decimals),
fees, and a deposit helper.
- Adopted dynamic block weight/length configuration (5 MB blocks) and
re-exported gas-to-weight constants.

- Improvements
- Switched all runtimes and pricing parameters from UNIT/NANO_UNIT to
HAVE/GIGAWEI.
- Updated deposits, fees, and rewards to HAVE-based values across
modules (including StorageHub and Snowbridge).
- Made existential deposit runtime-configurable; enabled zero-ED mode on
selected networks.
- Updated metadata hash and token metadata to reference HAVE (symbol
wHAVE, 18 decimals).

feat(operator): ✨ Multi-runtime support (#38) 
Add support for multiple runtimes: `stagenet`, `testnet` & `mainnet`.

- Moved common types to `datahaven-runtime-common` crate.
- Made the node's command & service code generic over different
runtimes. Each runtime has a `dev` & `local` genesis config preset.
- More types / constants can be moved to the `datahaven-runtime-common`
crate ... this will be done in subsequent PRs.
