🔧 fix: MCP Selection Persist and UI Flicker Issues (#9324)

* refactor: useMCPSelect

    - Add useGetMCPTools to use in useMCPSelect and elsewhere hooks for fetching MCP tools
    - remove memoized key
    - remove use of `useChatContext` and require conversationId as prop

* feat: Add MCPPanelContext and integrate conversationId as prop for useMCPSelect across components

- Introduced MCPPanelContext to manage conversationId state.
- Updated MCPSelect, MCPSubMenu, and MCPConfigDialog to accept conversationId as a prop.
- Modified ToolsDropdown and BadgeRow to pass conversationId to relevant components.
- Refactored MCPPanel to utilize MCPPanelProvider for context management.

* fix: remove nested ternary in ServerInitializationSection

- Replaced conditional operator with if-else statements for better readability in determining button text based on server initialization state and reinitialization status.

* refactor: wrap setValueWrap in useCallback for performance optimization

* refactor: streamline useMCPSelect by consolidating storageKey definition

* fix: prevent clearing selections on page refresh by tracking initial load completion

* refactor: simplify concern of useMCPSelect hook

* refactor: move ConfigFieldDetail interface to common types for better reusability, isolate usage of `useGetMCPTools`

* refactor: integrate mcpServerNames into BadgeRowContext and update ToolsDropdown and MCPSelect components
