- Add localization support for MCP features
- Refactor components for better reusability
- Update types and add MCP-related mutations
- Fix small issues with Actions and AgentSelect
- Refactor AgentPanelSwitch and related components to use new
  AgentPanelContext to reduce prop drilling

* chore: import order

* chore: clean up import statements and unused var in ActionsPanel component

* refactor: AgentPanelContext with actions query, remove unnecessary `actions` state

- Added actions query using `useGetActionsQuery` to fetch actions based on the current agent ID.
- Removed now unused `setActions` state and related logic from `AgentPanelContext` and `AgentPanelSwitch` components.
- Updated `AgentPanelContextType` to reflect the removal of `setActions`.

* chore: re-order import statements in AgentConfig component

* chore: re-order import statements in ModelPanel component

* chore: update ModelPanel props to consolidated props to avoid passing unnecessary props

* chore: update import statements in Providers index file to include ToastProvider and AgentPanelContext exports

* chore: clean up import statements in VersionPanel component

* refactor: streamline AgentConfig and AgentPanel components

- Consolidated props in AgentConfig to only include necessary fields.
- Updated AgentPanel to remove unused state and props, enhancing clarity and maintainability.
- Reorganized import statements for better structure and readability.

* refactor: replace default agent form values with utility function

- Updated AgentsProvider, AgentPanel, AgentSelect, and DeleteButton components to use getDefaultAgentFormValues utility function instead of directly importing defaultAgentFormValues.
- Enhanced the initialization of agent forms by incorporating localStorage values for model and provider in the new utility function.

* chore: comment out rendering MCPSection
