Implement comprehensive localization framework with English and Finnish support

- Add flutter_localizations dependency and l10n configuration
- Create ARB files for English (en) and Finnish (fi) translations
- Localize UI strings across all major components:
  * Navigation drawer and page titles
  * Scoring interface (arrows per end, ruleset names)
  * Scorecard headers (End, Arrows, Sum of 3/6, Accumulative)
  * Keypad functional buttons (CLEAR/TYHJENNÄ, CLOSE/SULJE)
  * Settings page placeholder content
  * Dialog messages and confirmation prompts
- Preserve universal archery scoring notation (X, 10, 9, M remain unlocalised)
- Use authentic Finnish archery terminology throughout
- Configure main app with proper localization delegates and supported locales
- Generate localization classes automatically via flutter_localizations

+/// Callers can lookup localized strings with an instance of AppLocalizations

+/// project’s Runner folder.
+///
+/// Next, select the Information Property List item, select Add Item from the
+/// Editor menu, then select Localizations from the pop-up menu.
+///
+/// Select and expand the newly-created Localizations item then, for each
+/// locale your application supports, add a new item and select the locale
+/// you wish to add from the pop-up menu in the Value field. This list should
