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.

+//! # Transaction Pause
+//!
+//! Allows dynamic, chain-state-based pausing and unpausing of specific extrinsics via call filters.
+//!
+//! ## Pallet API
+//!
+//! See the [`pallet`] module for more information about the interfaces this pallet exposes,
+//! including its configuration trait, dispatchables, storage items, events, and errors.
+//!
+//! ## Overview
+//!
+//! A dynamic call filter that can be controlled with extrinsics.
+//!
+//! Pausing an extrinsic means that the extrinsic CANNOT be called again until it is unpaused.
+//! The exception is calls that use `dispatch_bypass_filter`, typically only with the root origin.
+//!
+//! ### Primary Features
+//!
+//! - Calls that should never be paused can be added to a whitelist.
+//! - Separate origins are configurable for pausing and pausing.
+//! - Pausing is triggered using the string representation of the call.
+//! - Pauses can target a single extrinsic or an entire pallet.
+//! - Pauses can target future extrinsics or pallets.
+//!
+//! ### Example
+//!
+//! Configuration of call filters:
+//!
+//! ```ignore
+//! impl pezframe_system::Config for Runtime {
+//!   // …
+//!   type BaseCallFilter = InsideBoth<DefaultFilter, TxPause>;
+//!   // …
+//! }
+//! ```
+//!
+//! Pause specific all:
+#![doc = docify::embed!("src/tests.rs", can_pause_specific_call)]
+//!
+//! Unpause specific all:
+#![doc = docify::embed!("src/tests.rs", can_unpause_specific_call)]
+//!
+//! Pause all calls in a pallet:
+#![doc = docify::embed!("src/tests.rs", can_pause_all_calls_in_pallet_except_on_whitelist)]
+//!
+//! ## Low Level / Implementation Details
+//!
+//! ### Use Cost
+//!
+//! A storage map (`PausedCalls`) is used to store currently paused calls.
+//! Using the call filter will require a db read of that storage on each extrinsic.
