perf(kanvas): lazy-load non-critical sections and reduce unused JavaS…

[Azizah2023]

Description

Changes

• Lazy-load non-critical sections on the Kanvas page using import() + useEffect.
• Defer loading of non-critical Kanvas sections — Reviews, TeaserModal, KanvasFeatures, Catalog, KanvasBtn, and Platform — to reduce unused JavaScript and improve initial page performance.
• Performance before

• Performance after

Notes

• This is a clean replacement for previous work on branch fix/seo-alt-links-kanvas, which became noisy after syncing with master.

This PR fixes #
#7110

@Azizah2023 Please remove all unnecessary lint changes such as extra lines and spaces, and keep only the original logic.

Checks are currently failing, possibly due to the latest Gatsby update
Other than that, the changes look good to me @Azizah2023

@Azizah2023
Please ensure that your commit messages are meaningful rather than repeating the same message, as we need a clear history of changes. Finally, I noticed some files only contain formatting updates (like spacing). Please revert those specific modifications so we can keep the pull request focused strictly on functional code changes.
