feat(web): add network subpages and subdomains listing page

- Add /subdomains page listing all 20 PezkuwiChain subdomains
- Add Back to Home button to Subdomains page
- Create NetworkPage reusable component for network details
- Add 7 network subpages: /mainnet, /staging, /testnet, /beta, /alfa, /development, /local
- Update ChainSpecs network cards to navigate to network subpages
- Add i18n translations for chainSpecs section in en.ts
- Add SDK docs with rebranding support (rebrand-rustdoc.cjs)
- Add generate-docs-structure.cjs for automatic docs generation
- Update shared libs: endpoints, polkadot, wallet, xcm-bridge
- Add new token logos: TYR, ZGR, pezkuwi_icon
- Add new pages: Explorer, Docs, Wallet, Api, Faucet, Developers, Grants, Wiki, Forum, Telemetry
