feat: add adapter documentation link button

Add 'View Docs' button that links to the corresponding adapter's
documentation page via link.langbot.app short links.

Appears in:
- Wizard adapter selection cards (Step 0)
- Wizard bot config card header (Step 1)
- Bot create/edit form (adapter config section)

Supports all 7 languages (en/zh-Hans/zh-Hant/ja/th/vi/es).
Doc links auto-resolve to the correct language based on UI locale.
