chore(deps): Update golangci-lint to 2.7.2

[zak-pawel]

Summary

In this PR:

• I bumped the .golangci-lint from v2.5.0 to v2.7.2.
• I refined the current config to make it look as close as possible to https://github.com/golangci/golangci-lint/blob/main/.golangci.reference.yml to facilitate future diffs.
• I fixed new findings:
