Summary by Sourcery

Align documentation with updated AstrBot WebUI labels and navigation across English and Chinese guides.

Documentation:

• Update UI menu names and navigation paths in English documentation to match current WebUI labels for configuration, platforms, providers, agents, plugins/extensions, logs, and settings.
• Update Chinese documentation to reflect new UI terminology for model providers, configuration files, platforms, logs, agents, skills, and proactive tasks.
• Clarify locations of computer use, sandbox, knowledge base, web search, unified webhook, and self-hosted T2I settings in both language docs to match the latest UI.

Hey - I've left some high level feedback:

• In a couple of markdown files (e.g., docs/zh/use/proactive-agent.md and docs/zh/use/astrbot-agent-sandbox.md), a BOM-like character was introduced before the top-level # heading (+# ...); it’s better to remove this to avoid rendering or tooling issues.
• Now that most UI labels have been updated, it’s worth doing a quick pass for remaining occurrences of the old names (e.g., 服务提供商页面 vs. 模型提供商页面, Configuration vs. Config) to keep terminology fully consistent across the docs.

## Overall Comments
- In a couple of markdown files (e.g., `docs/zh/use/proactive-agent.md` and `docs/zh/use/astrbot-agent-sandbox.md`), a BOM-like character was introduced before the top-level `#` heading (`+# ...`); it’s better to remove this to avoid rendering or tooling issues.
- Now that most UI labels have been updated, it’s worth doing a quick pass for remaining occurrences of the old names (e.g., `服务提供商页面` vs. `模型提供商页面`, `Configuration` vs. `Config`) to keep terminology fully consistent across the docs.
