Clarify moved plugin skip metadata in Cypress suites

[utsavsomaiya]

Summary

• clean up stale/corrupted skip comments in the moved plugin test suites
• make skip reason explicit in suite titles for both history and navigate
• remove redundant inner it.skip(...) calls under describe.skip(...) in navigate.spec.js
• trim unused imports in navigate.spec.js

Why

These suites are intentionally skipped because ownership moved to livewire/livewire, but the current metadata is noisy and partially corrupted. This keeps the intent clear for maintainers.

Testing

• npm run vitest
• npm run build
