prepare release: staking config, proguard fixes, icons and build cleanup

- Add subquery endpoints for staking-rewards, history, staking APIs
- Add identityChain, stakingWiki, pushSupport to chain config
- Remove versionNameSuffix/applicationIdSuffix from releaseMarket build
- Fix privacy/terms URLs to use .html extension
- Strengthen proguard rules for Retrofit, SR25519, Substrate SDK,
  WalletConnect, Google Drive, Navigation and crypto classes
- Update launcher icons for debug and release variants
