feat: initial Pezkuwi Apps rebrand from polkadot-apps

Rebranded terminology: - Polkadot → Pezkuwi - Kusama → Dicle - Westend → Zagros - Rococo → PezkuwiChain - Substrate → Bizinikiwi - parachain → teyrchain Custom logos with Kurdistan brand colors (#e6007a → #86e62a): - bizinikiwi-hexagon.svg - sora-bizinikiwi.svg - hezscanner.svg - heztreasury.svg - pezkuwiscan.svg - pezkuwistats.svg - pezkuwiassembly.svg - pezkuwiholic.svg
