Block endpoints with many transactions fail with rate limit error

[m-Peter]

Closes: #547

Description

To avoid this, instead of re-using the eth_getTransactionByHash method directly, we extract its logic to a helper function, avoiding the possibility of rate-limit errors for blocks with many transactions.

The pull request introduces changes to the BlockChainAPI methods, focusing on transaction and block data retrieval. It replaces direct calls to GetTransactionByHash with a new method, prepareTransactionResponse, enhancing code structure. The prepareBlockResponse method has also been simplified by removing the context parameter. These modifications aim to improve code readability and maintainability by centralizing transaction handling and reducing redundancy.

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  -- I pushed a fix in commit <commit_id>, please review it.
  -- Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  -- @coderabbitai generate unit testing code for this file.
  -- @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  -- @coderabbitai generate interesting stats about this repository and render them as a table.
  -- @coderabbitai read src/utils.ts and generate unit testing code.
  -- @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  -- @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
