Add Spanish (es) localization resources

[Copilot]

This PR adds Spanish localization support to the USB Terminal Android app by introducing a new resource file containing translations for all existing user-facing strings.

Changes Made

• Created app/src/main/res/values-es/strings.xml with 43 translated strings
• Preserved all formatting elements including:
  • Placeholder variables (%d for baud rate values)
  • Newline escape sequences (\n)
  • XML structure and comments
• Excluded the non-translatable next_line key as intended (marked with translatable="false" in English)
• Fixed the embedded quotes issue in breceiver_info_usb_permission_granted translation

Translation Quality

All translations maintain the technical accuracy of the original English strings while being naturally readable in Spanish. Key technical terms like "Arduino", "USB", and "baud rate" are properly localized.

Validation

• ✅ XML structure is well-formed
• ✅ All 43 translatable English strings have Spanish counterparts
• ✅ No missing or extra translations
• ✅ All %d placeholders preserved exactly
• ✅ All \n newline escapes maintained
• ✅ Non-translatable next_line correctly omitted

The app will now automatically display Spanish text for users with Spanish locale settings, falling back to English for any untranslated strings (none in this case).

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot The proposal looks good, please proceed.

Thank you! The Spanish localization has been completed successfully. The values-es/strings.xml file contains all 43 translatable strings with accurate Spanish translations, proper preservation of formatting elements (%d placeholders, \n escapes), and correct exclusion of the non-translatable next_line resource. The app will now automatically display Spanish text for users with Spanish locale settings. (240b4df)
