feat: Rebrand Polkadot/Substrate references to PezkuwiChain

This commit systematically rebrands various references from Parity Technologies'
Polkadot/Substrate ecosystem to PezkuwiChain within the kurdistan-sdk.

Key changes include:
- Updated external repository URLs (zombienet-sdk, parity-db, parity-scale-codec, wasm-instrument) to point to pezkuwichain forks.
- Modified internal documentation and code comments to reflect PezkuwiChain naming and structure.
- Replaced direct references to  with  or specific paths within the  for XCM, Pezkuwi, and other modules.
- Cleaned up deprecated  issue and PR references in various  and  files, particularly in  and  modules.
- Adjusted image and logo URLs in documentation to point to PezkuwiChain assets.
- Removed or rephrased comments related to external Polkadot/Substrate PRs and issues.

This is a significant step towards fully customizing the SDK for the PezkuwiChain ecosystem.

+## Asset Transaction Payment Pallet
+
+This pallet allows runtimes that include it to pay for transactions in assets other than the
+native token of the chain.
+
+### Overview
+It does this by extending transactions to include an optional `AssetId` that specifies the asset
+to be used for payment (defaulting to the native token on `None`). It expects an
+[`OnChargeAssetTransaction`] implementation analogously to [`pezpallet-transaction-payment`]. The
+included [`FungiblesAdapter`] (implementing [`OnChargeAssetTransaction`]) determines the fee
+amount by converting the fee calculated by [`pezpallet-transaction-payment`] into the desired
+asset.
+
+### Integration
+This pallet wraps FRAME's transaction payment pallet and functions as a replacement. This means
+you should include both pallets in your `construct_runtime` macro, but only include this
+pallet's [`TransactionExtension`] ([`ChargeAssetTxPayment`]).
