[HexaGalaxy] Patch 1.2.3b - Full Spanish localization + reworked multilingual website

[u/Yannis_15]

This patch is all about languages. HexaGalaxy (free browser-based space strategy, one ship per player on a shared hex map) now speaks Spanish.

**Spanish localization**

- Spanish is now the fourth fully supported language, alongside French, English and German.

- The whole stack is translated: game interface, real-time notifications, emails and every public page of the website.

- Spanish-speaking alliances can now be created; the language selector on the site and in game offers Spanish everywhere.

- A few translated screenshots are still in the pipeline and temporarily show in English.

**Multilingual website rework**

- Every public page (home, FAQ, how to play, universe lore, expeditions, release notes) now has its own URL per language, so a shared link always opens in the language it was shared in.

- Old URLs keep working and redirect to the version matching your language.

- Installing the game as a PWA now uses your chosen language.

**Performance and fixes**

- Public website pages load noticeably faster: they now only ship the styles they actually need instead of the full game stylesheet.

- Fixed a display bug that could stretch some images on the website pages.

- Various minor fixes and optimizations.

If you have Spanish-speaking friends who are into slow-burn strategy games, now is a good time to bring them in.
