fix: resolve keyboard translation crash and reset (#630)

[prince-0408]

Summary

Resolves the keyboard translation crash and reset bug described in #630. The crash was caused by the app attempting to load TranslationData.sqlite from the bundle, which had been removed from target resource lists in #593. Additionally, empty command inputs or empty database translation query results caused index out-of-range crashes during string processing.

This PR restores the database to the main target, sets up a dynamic copy to the shared container on startup, and hardens the query methods to handle empty states gracefully.

File Changes

File	Action	Description of Changes
project.pbxproj	Modified	• Adds TranslationData.sqlite file reference. • Includes the database file under the resources build phase of the main Scribe app target. • Intentionally excluded from individual keyboard extensions to optimize app size.
AppDelegate.swift	Modified	• Implements copyTranslationDataToSharedContainer() helper method. • Copies TranslationData.sqlite dynamically from the main bundle to the Shared App Group container on launch. • Compares modification dates to overwrite and sync files on app updates.
LanguageDBManager.swift	Modified	• Configures translations manager to first open TranslationData from the Shared App Group container. • Removes force-unwrap (!) on path checks inside openDBQueue to handle missing resources safely.
Translate.swift	Modified	• Adds a guard against empty input strings inside queryWordToTranslate() to prevent out-of-bounds string slicing. • Safely accesses query outputs using .first and empty checks instead of direct [0] subscripting.
