feat(savedata): write back zenny/gzenny/CP to ZZ save blob

Browse Source 
Mirrors the read path added in 47277c7: updateSaveDataWithStruct now
flushes Zenny/GZenny/CP back to the blob for ZZ, using the same
`ok && off > 0 && off+size <= len(blob)` guard so unmapped modes remain
inert.

Tests lock down byte-level idempotence — the most important invariant
for save data. Parsing a live kirito ZZ blob and immediately writing
the struct back produces a byte-identical blob, so enabling these
fields cannot silently corrupt existing player saves on the next save
cycle. Additional coverage: round-trip through both paths, non-ZZ
modes never touch the blob bytes, and truncated blobs don't panic on
write.

### Added
- Parse zenny, gzenny and caravan points (CP) from the ZZ character save blob (offsets 0xB0, 0x1FF64, 0x212E4 — sourced from Chakratos/mhf-save-manager, validated against a live HR999 save). Exposed as `CharacterSaveData.Zenny/GZenny/CP` alongside the existing `current_equip` pointer; read-only for now. Pre-ZZ modes remain unmapped to avoid corrupting unverified layouts.
- Parse and write zenny, gzenny and caravan points (CP) in the ZZ character save blob (offsets 0xB0, 0x1FF64, 0x212E4 — sourced from Chakratos/mhf-save-manager, validated against a live HR999 save). Exposed as `CharacterSaveData.Zenny/GZenny/CP` alongside the existing `current_equip` pointer. Write path is byte-idempotent (verified against a live blob). Pre-ZZ modes remain unmapped to avoid corrupting unverified layouts.
- Chinese (`zh`) language strings for chat commands, guild mails, cafe/timer broadcasts and prayer beads. Note: Shift-JIS wire encoding only covers characters shared with Japanese — simplified-only glyphs may fail to encode.
- Server-side multi-language support ([#188](https://github.com/Mezeporta/Erupe/issues/188)): each player picks their own language with `!lang <en|jp|fr|es|zh>`, persisted per user (migration `0022_user_language`) and loaded on login. Chat replies, guild invite mails, and cafe/timer broadcasts are served in that language via `Session.I18n()`. Quest and scenario JSON text fields now accept either a plain string (unchanged) or a `{"jp":"...","en":"...","fr":"..."}` map; the compiler resolves per session and the quest cache is keyed by `(questID, lang)`. Existing single-language JSONs and `.bin` round-trips remain byte-identical. Shift-JIS wire encoding still applies (ASCII/kana/CJK only). Raviente world-wide broadcasts stay on the server default since they have no single session.
