fix: use correct locale keys in TutorialHelp component (fixes #348)

[colsonSung]

Summary

Fixes #348 — i18n keys displayed instead of translated text in the 'How Trimming Works' modal on Windows 11.

Root Cause

called translation keys that do not exist in any locale file:

Broken key	Used in component
tutorial.explanationBefore	Explanation paragraph
tutorial.explanationMiddle	Explanation paragraph
tutorial.explanationAfter	Explanation paragraph
tutorial.remove	Explanation paragraph
tutorial.covered	Explanation paragraph
tutorial.step1DescriptionBefore	Step 1 description
tutorial.step1DescriptionAfter	Step 1 description

The i18n loader's fallback returns the key itself when no translation is found, so users see literal strings like dialogs.tutorial.explanationBefore instead of readable text.

Fix

Replace the non-existent key chain with keys that already exist in all locale files (en, zh-CN, es):

• tutorial.explanation + tutorial.explanationRemove + tutorial.explanationCovered + tutorial.explanationEnd
• tutorial.step1Description (instead of split Before/After keys)

Files Changed

• src/components/video-editor/TutorialHelp.tsx — updated t() calls
• No locale file changes needed — all required keys already exist

Verification

npx tsc --noEmit passes with no errors.

Closes #348

📝 Walkthrough

Walkthrough

Consolidated fragmented translation keys in the TutorialHelp component by replacing multi-key text composition with single unified translation keys. The "Explanation" and "Steps" sections now use consolidated keys instead of before/middle/after patterns, reducing key sprawl and simplifying i18n string management.

Changes

Cohort / File(s)	Summary
Translation Key Consolidation src/components/video-editor/TutorialHelp.tsx	Replaced fragmented translation keys (tutorial.explanationBefore, tutorial.step1DescriptionBefore, etc.) with consolidated single keys (tutorial.explanation, tutorial.step1Description). Emphasized segments now use dedicated keys (tutorial.explanationRemove, tutorial.explanationCovered) instead of inline composition.

Poem

🔑✨ Keys once scattered, now they gleam,
Fragmented pieces form a dream,
No more broken strings in sight,
Translation flows, clean and right! 🌟

lowkey looks like a solid fix for that windows 11 bug—the i18n keys showing up instead of actual text. consolidating these makes sense from a maintenance perspective too; less surface area for things to go sideways. nit: just make sure the new translation keys are actually defined in your i18n files, otherwise you've just moved the problem around 😄

⚠️ Potential issue | 🟡 Minor

Missing separator before tutorial.explanationEnd (renders like coveredby).

Line 43 concatenates directly after the highlighted tutorial.explanationCovered, so en/es text joins words. lowkey tiny but very visible in UI copy.

💡 Minimal fix

-							<span className="text-[`#ef4444`] font-bold"> {t("tutorial.explanationCovered")}</span>
-							{t("tutorial.explanationEnd")}
+							<span className="text-[`#ef4444`] font-bold"> {t("tutorial.explanationCovered")}</span>{" "}
+							{t("tutorial.explanationEnd")}

Hey! I was looking at this issue too and noticed a couple things worth flagging.

Inline styling regression: The original component intentionally splits the explanation into explanationBefore / remove / explanationMiddle / covered / explanationAfter so it can wrap "remove" and "covered" in bold red <span> elements with connecting text between them. This PR drops the explanationMiddle segment, so the two bold spans render back-to-back without the linking sentence fragment.

<kbd> element lost: Similarly, the original splits step1DescriptionBefore / <kbd>T</kbd> / step1DescriptionAfter to render a styled keyboard shortcut. This PR replaces that with a single flat step1Description string, so the <kbd> styling is gone.

3 of 5 locales break: en, es, and zh-CN already have the "correct" keys (explanationBefore, remove, explanationMiddle, etc.). This PR changes the component to use the fr/tr key names, which means en/es/zh-CN would now show raw keys instead — flipping the bug to the other locales.

The root cause is that the fr and tr locale files were contributed with different key names. An alternative fix would be to update fr/dialogs.json and tr/dialogs.json to match the key structure that en/es/zh-CN already use, preserving the component's inline styling. Just wanted to flag this in case it's helpful!
