Migrate UI strings to $tf for translation support

[zeedif]

Summary

This PR updates the main project to use the new $tf translation helper from livesync-commonlib, replacing hardcoded strings with translation keys. This change centralizes UI text for easier community translations.

Key Changes

• Migrated All Modified Strings
  • Replaced direct text in components/logic with $tf calls (e.g., "Pause" → tf("logPane.pause")).
• Submodule Update
  • Includes the latest livesync-commonlib version with the new $tf utility.

Why This Matters

• Spanish Support: Enables loading translations from rosetta.ts for Spanish-speaking users.
• Contributor Workflow: Simplifies adding new languages via centralized keys.

Next Steps

• Finalize remaining string migrations (WIP).
• Update documentation for translation contributors.
