fix: standardize Chinese token terminology

[Ill-donut]

Summary

• Standardize Chinese model/NLP terminology with position-aware casing: use Token only when the term itself begins a sentence, title, label, or definition fragment; otherwise use lowercase token in Chinese text.
• Standardize authentication credentials as 令牌, while preserving identifiers, code literals, external UI labels, and deliberate UI casing.
• Align quoted Dify UI fields with the coordinated UI branch.
• Correct adjacent terminology such as cryptocurrency 代币 and tokenizer 分词器.

The two model-token corrections in zh/quick-start.mdx remain in #945 and are intentionally excluded here to avoid duplicate changes.

UI alignment

Coordinated UI branch: langgenius/dify:fix/zh-ui-token-terminology

• Token-first strings remain capitalized: Token 用量, Token 输出速度, Token/秒, Token 数
• Strings with preceding Chinese text use lowercase: 耗费 token, 使用 token, 花费 token
• Running prose uses lowercase token
• appLog.table.header.tokens remains TOKENS as an intentional all-caps table header, consistent with the source locale and neighboring headers
• workflow.nodes.llm.resolution.high/low: High/Low, 高/低, and 高/低 in en/zh/ja
