refactor(prompts-chara): tighten wording + handle in-place L10N drift (Project-N-E-K-O#1116)

Wording / consistency fixes in `_L10N` and the prompt template:
- `客气` → `客套`（zh / zh-TW / ja `遠慮は不要` → `他人行儀は不要`）；en/ko/ru
  原本就是 formality 语义，无需改动
- en `char_setting` 补成双形 `settings/character setting`，与其它 locale 对齐
- Avatar Overlay / Memory Integrity 从第二人称改回第三人称，整段保持口吻一致
- 修 `shares an screen capture` → `shares a screen capture` typo

Normalizer 之前的 `_normalize_default_prompt_text` 只能吃下整行新增 / 整行
删除，无法处理 in-place 字句修改。今天这批改动里有 5 处都是就地改字
（`无需客气` / `無需客氣` / `遠慮は不要` / `"character setting"` / `an screen capture`），
任意一处不兜住，所有今天之前装过 Xiao8 的用户其 stored prompt 在比对时
都会被判非默认 → `is_default_prompt` 返 False → 切语言时不再自动本地化。

引入 `legacy_text_replacements` 元组，比较前先把旧字串规范化到当前字串。
后续再做 wording tweak，往该元组加一行即可。

顺手把 `added_context_lines` 同步到 Memory Integrity 新文案，并保留旧文案
以兼容上一版 stored prompt。

测试加了两条覆盖 in-place wording drift 与 typo 兜底，全 7/7 通过。
