feat: complete Pezkuwi rebrand - remove other networks

- Remove all Polkadot ecosystem networks from chain selector
- Keep only: Pezkuwi Relay Chain, Zagros Relay Chain, Pezkuwi Beta Testnet
- Update extension ID from polkadot-js to pezkuwi
- Update PhishingDetected to use Pezkuwi branding
- Update metadataMock: Westend → Zagros, WND → ZGR
- Disable Ledger chains (no Pezkuwi Ledger app yet)
- Update Identicon to handle pezkuwi icon theme
- Clean up translation files

Breaking: Extension now only supports Pezkuwi networks
