CI: add dupword linter and fix issues

[cce]

Summary

Inspired by helpful open source contributions in #6463 and #6471 this adds the "dupword" linter and also fixes all the issues it found.

This will enforce new duplicate words don't creep into the codebase, obviating the need for future contributions like those in #6463 and #6471.

As a bonus, this PR also enables the misspell linter for test code (it was already running on non-test code) to pre-empt the need for typo PR fixes in the future.

Test Plan

Linter should pass

Pull Request Overview

This PR adds the "dupword" linter to enforce detection of duplicate words in code comments, inspired by external contributions. It addresses all identified duplicate word issues throughout the codebase by correcting comments and documentation that contained repeated words.

• Configures the dupword linter in .golangci.yml to check comments only, with an exception for "long long"
• Fixes duplicate words in comments across 40+ files spanning utilities, network, ledger, data structures, and daemon components
• Updates the golangci-lint version to support the new linter
