fix: font fallback for deploy, localized og:tags

[Hugo0]

Summary

• Graceful font fallback: generate_share_images.py now tries multiple font paths (Ubuntu/Fedora/Arch) and never crashes on missing fonts
• Localized og:title/og:description: uses native-language challenge text from language configs (e.g. "Wordle Deutsch — 5/6") instead of hardcoded English
• Lint cleanup: fix unused variable and ternary lint warnings

Test plan

• pnpm test — all 81 tests pass
• ruff format + ruff check — clean
• Verify share images generate correctly on deploy (font fallback)
• Check og:tags render correctly for non-English languages (view page source)

Summary by CodeRabbit

• Bug Fixes

  • Enhanced font resolution system with robust fallback handling and improved platform compatibility. Fonts now gracefully fall back to default options when unavailable, with better error reporting.

• New Features

  • Customized share metadata that reflects individual game outcomes. Share messages now include outcome-specific titles and descriptions.

Cohort / File(s)	Summary
Font Resolution & Image Generation scripts/generate_share_images.py	Introduces _resolve_font() helper for cross-platform font discovery, replaces hard-coded font paths with candidate lists, adds module-level logging, dynamically resolves font constants at import time with fallbacks, enhances get_font() to gracefully default to Pillow's built-in font on failure, simplifies command-line argument parsing for target languages.
Share Metadata & UI Logging webapp/templates/game.html	Updates share metadata logic to generate outcome-specific titles and descriptions (win/loss/challenge states), adds language initialization logging (name, word list sizes, character set, daily word), updates issue tracker links from /new/choose to root issues endpoint.
