Translate the store entry into the fifteen locales the store uses

[cvaghela]

IceWhale's maintainer asked for more languages on the upstream PR (IceWhaleTech/CasaOS-AppStore#1024). Their own apps — Jellyfin, Plex, Syncthing, Immich — all carry the same fifteen locales on the same three fields, so that is the set used here.

What is translated

Field	Locales	Note
tagline	15
description	15
release_notes	15
tips.before_install	15	Most store apps leave this English. It is the text that stops a failed install here, so it is translated.
title	1	Stays en_US — it is a product name.

en_US en_GB de_DE el_GR fr_FR hr_HR it_IT ja_JP ko_KR nb_NO pt_PT ru_RU sv_SE tr_TR zh_CN

Product names, monitor names (Plex local), environment variables, ports and the on-screen URL Locked label stay English in every locale. They are strings a user types or reads on screen, not prose — a translated Plex local names a monitor the pairing rule will not recognise, and a translated "URL Locked" sends someone hunting for text the interface never shows.

These translations have not been reviewed by native speakers. They are unlikely to be worse than what the store already carries, but that is the honest status.

Two guards had to move

Translating the text created two new ways for it to go quietly wrong, so both are closed in the same change.

check-release.py was testing version not in notes_text across the whole release_notes block. With fifteen locales in there, updating one satisfies the test while the other fourteen describe the previous release — the same staleness this check was added for after the store's What's New sat at 1.3.2 for three releases, only harder to see. It now checks each locale separately, and additionally requires all four translated fields to carry an identical locale set, so a language added to the description but not the release notes fails rather than shipping half-translated.

sync-appstore-upstream.py swapped the install-Kuma sentence in English only, which was correct while the tips were English only. One sentence differs between the two stores: ours carries a single app so it points at the official ZimaOS store for Uptime Kuma, theirs carries Kuma itself. Translating the tips without making the swap per-locale would have shipped fourteen locales telling IceWhale's own users to go and find Kuma in somebody else's store. The swap is now a per-locale table, every entry required, and the render aborts if any mention of the wrong store survives.

Verification

Both guards were mutation-tested — the fault reintroduced, the guard watched to fail by name, then restored:

Mutation	Result
zh_CN release note left at 1.5.0	FAIL: … release_notes[zh_CN] does not mention 1.5.1
ko_KR dropped from tagline only	FAIL: … tagline locales do not match description (missing: ko_KR)
ja_JP install-Kuma sentence reworded	FAIL: … has no ja_JP install-Kuma sentence matching KUMA_STORE_SENTENCE

Also run, all green: test-reporters.sh (12 passed), check-release.py, check-compose-networks.py, check-service-additions.py, and docker compose config --quiet on the app-store file (on the ZimaOS host, since Docker is not on this machine). A structural parse there confirms 7 services, title at one locale and the other four fields at fifteen.

Not in this change

The upstream PR is still pinned at 1.3.2 — amd64-only, no AI reporters, three releases behind. Refreshing it to 1.5.1 is the other half of answering that comment and needs a separate push to the fork.
