Pull request overview

This PR upgrades the pallet-block-reward token distribution model from a fixed, hard-coded beneficiary split to a configurable “token sinks” list that can target either Substrate pallet pots or EVM H160 addresses (via runtime-provided address mapping). It also introduces a one-time migration path from the legacy on-chain config, updates the runtimes/chain-specs to seed the new sinks, and refreshes benchmarks/weights/tests accordingly.

Changes:

• Replace legacy reward distribution configuration with Sinks (bounded list of {target, share}) + validation, events, and new weight functions.
• Add v3 storage migration to delete legacy config and adopt runtime-provided migration sinks; update runtimes + chain-spec genesis config to use those sinks.
• Regenerate benchmarking + weights and update tests/mocks to cover sink validation, distribution behavior, and migration behavior.

File	Description
runtime/peaq/src/lib.rs	Bumps runtime spec_version, wires pallet_block_reward to new sinks config + address mapping, adds migration sinks constants.
runtime/peaq-dev/src/lib.rs	Same as peaq runtime: new sinks wiring, spec_version bump, alloc String return update.
runtime/krest/src/lib.rs	Same sinks wiring for krest, with krest-specific sink list preserving legacy split.
pallets/block-reward/src/lib.rs	Core refactor: replaces config storage with Sinks, adds set_sinks, validation, and sink-based distribution logic.
pallets/block-reward/src/types.rs	Introduces Sink, RewardTarget, SinkPalletId, compile-time distribution check helper, and address mapping trait.
pallets/block-reward/src/migrations.rs	Replaces old migration with v3 migration adopting runtime-provided sink list when legacy storage is detected.
pallets/block-reward/src/benchmarking.rs	Updates benchmarks for set_sinks and sink-based distribution.
pallets/block-reward/src/weights.rs	Updates autogenerated weights to new extrinsics/paths (set_sinks, distribute_imbalances).
pallets/block-reward/src/weightinfo.rs	Updates WeightInfo trait to match new benchmarking/weights functions.
pallets/block-reward/src/tests.rs	Reworks tests to validate sink rules, distribution correctness, genesis behavior, and burn fallback behavior.
pallets/block-reward/src/mock.rs	Updates mock runtime to support sinks + address mapping, and adds fixtures for migration tests.
pallets/block-reward/Cargo.toml	Adjusts dependencies for new types/tests (e.g., sp-core non-optional, adds hex-literal).
pallets/address-unification/src/lib.rs	Exposes convert_impl publicly so runtimes can reuse the address mapping implementation.
node/src/parachain/peaq_chain_spec.rs	Seeds genesis block-reward sinks using runtime-provided BlockRewardMigrationSinks.
node/src/parachain/krest_chain_spec.rs	Same genesis sink seeding for krest.
node/src/parachain/dev_chain_spec.rs	Same genesis sink seeding for dev runtime.
Cargo.lock	Locks new dependency (hex-literal).
