Add Simplified Chinese (zh) language resources: yoga_msgs, dosha_msgs, raja_yoga_msgs

[BloodyOrangeMan]

What

Complete Simplified Chinese (zh-Hans) translations of three prose resource families, following the existing _<lang> file convention:

• yoga_msgs_zh.json — all 284 entries (name / rule / effect, same keys and array arity as yoga_msgs_en.json)
• dosha_msgs_zh.json — all 9 entries
• raja_yoga_msgs_zh.json — all 3 entries

'zh' is deliberately not registered in const.available_languages yet: list_values_zh.txt and msg_strings_zh.txt don't exist, so registering the language would break full-UI language switching. The JSON families are loadable per-file through the existing readers (e.g. raja_yoga.get_raja_yoga_resources) in the meantime; we'd like to contribute the remaining files in a follow-up.

Translation conventions

• Yoga/doṣa names kept as transliterated proper nouns ("Vosi Yoga" stays "Vosi Yoga") — Chinese Vedic-astrology communities cite them by Sanskrit name.
• Rule text in plain technical Chinese (house = 宫, sign = 座-suffixed, aspect = 相位, exaltation/debilitation = 庙旺/落陷, Rahu/Ketu = 罗睺/计都 per classical 七政四余 usage).
• Effect text in modern register with 命主 ("the native") as subject.
• Nakṣatra references Sanskrit-primary, glossed with the classical 28-mansion (二十八宿) equivalents.
• Sanskrit terms without settled Chinese equivalents (kendra, navamsa, dusthana, …) kept as-is inside sentences.

Terminology choices were grounded in a survey of published Chinese-language Vedic astrology sources (mainland and Taiwan). The translations are model-drafted under those conventions with per-batch back-translation review for meaning fidelity (house numbers, from-Sun/from-Moon counting, negations), for use in an AGPL desktop app built on PyJHora. Native-speaker review and corrections are very welcome — we'll happily iterate.

English source-text typos noticed while translating

Translated faithfully as-is; listing here in case fixes are welcome upstream (happy to send a separate PR for these against the _en files):

• Spelling: "Aquariius" (sasa_yoga), "Sagitarius" / "Capricornn" (hamsa_yoga), "resepcted" (go_yoga), "autere" (saarada_yoga), "maleefics" (asubha_yoga)
• "this is yoga is present" + a stray leading ] (bheri_yoga); "You will wealth and vehicles" (duradhara_yoga, missing verb)
• Stray digits that look like leaked footnote markers: "Jupiter32" (kaahala_yoga), "exchange35" (devendra_yoga)
• gaja_kesari_yoga and guru_mangala_yoga carry their raw snake_case key as element [0] where every sibling has a Title Case display name
• pushkala_yoga numbers two conditions "(2)"; unpaired quotes in subha/asubha/guru_mangala entries
