fix : added request timeout to translateText

[tmdeveloper007]

Closes #2061.

Summary of What Has Been Done:
Added an AbortController with 10-second timeout to the translateText function.

Changes Made:

• Wrap fetch call with AbortController
• 10000ms timeout triggers abort
• clearTimeout called in both success and error paths
• AbortError is caught separately and logs a warning (not error)
• Returns original text on timeout (same graceful fallback)
• Added test verifying AbortController is passed to fetch

Impact it Made:

• Prevents indefinite hangs during network issues
• Improves UX when MyMemory API is slow or unavailable
• All 8 tests pass
