FN-7898: add in-chat thinking-level control next to the attach button
Adds a Brain-icon popover control in the chat composer that lets users change an existing session's reasoning-effort level mid-conversation, extending the existing create-time-only thinking-level picker.
- Add ChatThinkingLevelControl component (Brain-icon trigger + popover) wired into ChatView's direct-session composer, gated to non-CLI model-loop sessions only
- Extend PATCH /api/chat/sessions/:id to accept an optional thinkingLevel field, validated via existing validateThinkingLevel helper; null/empty string explicitly clears back to the inherited default, omitting the key leaves it untouched
- Add useChat().setSessionThinkingLevel hook method to call the new PATCH capability
- Add i18n strings (thinkingLevelButton) across all locales and regenerate packages/i18n/src/resources.d.ts
- Add changeset for @runfusion/fusion (minor) and update docs/dashboard-guide.md
