Update July release documentation

Created by: ihsraham

Summary

• Add release documentation for the July 07, July 04, and July 03 WDK package updates, plus the existing July 01 entries.
• Update EVM wallet docs for signer-backed accounts, private-key accounts, contract-creation transactions, and ERC-7702 authorization/delegation helpers.
• Update TRON wallet docs for arbitrary transaction support covering native TRX transfers, smart-contract call descriptors, and pre-built TronWeb transactions.
• Update Bitfinex pricing docs for direct Bitfinex quote behavior after removal of the USD-pivot fallback.
• Keep Worklet Bundler usage pages on the prior workflow because the v1.0.0-beta.4 npm artifact is missing built CLI/API files; the changelog calls out the source changes and artifact caveat.
• Move swap-velora-evm v1.0.0-beta.6 to its actual June 30 release date and retain the React Native Core July 01 update.
