fix: use Vue tooltips for rank emojis

[tomatotomata]

Summary

Replaces the native title attributes on the rank and status emojis with the repository's existing v-tooltip directive. This makes the explanations appear through the same Vue tooltip system already used by the application, instead of relying on the delayed browser tooltip.

The change stays inside OverallRankEmoji.vue, keeps the existing messages, and registers the existing plugin for the component.

Fixes #305

Testing

• corepack yarn prettier src/components/OverallRankEmoji.vue --check passes after formatting.
• corepack yarn eslint src/components/OverallRankEmoji.vue passes.
• git diff --check passes.
• corepack yarn build was attempted, but did not finish within two minutes in this environment.

@tomatotomata - that's for the contribution! You have a merge conflict now, and did you want to move this PR out of draft, or were you waiting on something?

[tomatotomata]

Resolved the conflict against current main in 1e2b917. Upstream added a separate hasNeverSubmitted state, so I preserved that behavior and applied the same Vue tooltip treatment to both the new state and the existing old-data state. Prettier passes on the rebased file.

I also moved the PR out of draft. I had left it there because the full local build did not finish within the available window, but the branch is ready for the updated preview and review now.

@tomatotomata - could you tighten up the tooltip? We probably want 12px font size and no extra vertical padding (might require tighter line height)

[tomatotomata]

I tightened the tooltip styling for the rank emojis on commit 7dae847. The rank component now uses its own tooltip class, keeps the existing global tooltip sizing, sets the text to 12px, and removes the extra vertical padding. Prettier and the component ESLint check pass; the full Gridsome build timed out locally after two minutes. Do you think this is closer to the screenshot?
