fix: clarify Smart Wearable file size error message

[decentraland-bot]

Summary

• Root cause: ImportStep.tsx lacked a FileType.SMART_WEARABLE case in the FileTooBigErrorBuilderClient switch statement. Smart wearable upload errors fell through to the generic file_too_big default — which is a flat string key, not a nested .title/.message — resulting in a blank error title shown to users.
• Fix: Route FileType.SMART_WEARABLE → smart_wearable_too_big, which already has the correct message explaining the 3 MB limit applies to uncompressed content.
• UX improvement: Updated smart_wearable_too_big.title in all three locale files (en/es/zh) to make it explicit that the limit applies to uncompressed content, not the ZIP file itself.

Plan

Root Cause Analysis

In ImportStep.tsx, the switch on error.getType() had cases for WEARABLE, SKIN, EMOTE, and THUMBNAIL — but not SMART_WEARABLE. Smart wearable errors fell to:

default: {
  errorTranslationId = 'file_too_big'
}

The display block then accesses create_single_item_modal.error.file_too_big.title and .message. But file_too_big is a flat string in the JSON (not a nested object), so both resolve to undefined → blank error shown to user.

The translation smart_wearable_too_big already existed with the correct .message. Only the .title needed updating to distinguish between ZIP size and uncompressed size.

ImportStep.tsx — added explicit case:

case FileType.SMART_WEARABLE: {
  errorTranslationId = 'smart_wearable_too_big'
  break
}

en.json — updated title:

- "The file is too large and can't be uploaded"
+ "The uncompressed Smart Wearable content exceeds the size limit"

Testing

• Verified FileType.SMART_WEARABLE = "smart-wearable" exists in @dcl/builder-client dist types
• Verified FileType is already imported in ImportStep.tsx
• Verified smart_wearable_too_big has the correct .title/.message nested structure matching the pattern used to build the error display
• Pre-existing typecheck errors in local environment (@types/react-router-dom missing) are unrelated to these changes

Context

A user uploaded a Smart Wearable ZIP of 2.9 MB (under the 3 MB ZIP limit) but the upload was rejected because the uncompressed content was 3.7 MB. The error shown was blank/misleading.
