feat: implement localization system (#716)

* lib/localization: implement localization system

Locale files are placed in lib/localization/locales/. If you add a
locale, update manifest.json with available locales.

* Exclude locales from check spelling

* tests(lib/localization): add comprehensive translations test

* fix(challenge/metarefresh): enable localization

Signed-off-by: Xe Iaso <[e-mail]>

* fix: use simple syntax for localization in templ

Also localize CELPHASE into French according to the wishes of the
artist.

-				You are seeing this because the administrator of this website has set up <a
-	href="https://github.com/TecharoHQ/anubis"
->Anubis</a> to protect the server against the scourge of
-				<a href="https://thelibre.news/foss-infrastructure-is-under-attack-by-ai-companies/">
-					AI companies
-					aggressively scraping websites
-				</a>. This can and does cause downtime for the websites, which makes their
-				resources inaccessible for everyone.
+				{ localizer.T("ai_companies_explanation") }
 			</p>
 			<p>
-				Anubis is a compromise. Anubis uses a <a
-	href="https://anubis.techaro.lol/docs/design/why-proof-of-work"
->Proof-of-Work</a>
-				scheme in the vein of <a href="https://en.wikipedia.org/wiki/Hashcash">Hashcash</a>, a proposed
-				proof-of-work scheme for reducing email spam. The idea is that at individual scales the additional load is
-				ignorable, but at mass scraper levels it adds up and makes scraping much more expensive.
+				{ localizer.T("anubis_compromise") }
 			</p>
 			<p>
-				Ultimately, this is a hack whose real purpose is to give a "good enough" placeholder solution so that more
-				time can be spent on fingerprinting and identifying headless browsers (EG: via how they do font rendering)
-				so that the challenge proof of work page doesn't need to be presented to users that are much more likely to
-				be legitimate.
+				{ localizer.T("hack_purpose") }
 			</p>
 			<p>
-				Please note that Anubis requires the use of modern JavaScript features that plugins like <a
-	href="https://jshelter.org/"
->JShelter</a> will disable. Please disable JShelter or other such
-				plugins for this domain.

-				Sadly, you must enable JavaScript to get past this challenge. This is required because AI companies have
