fix: broadcast MCP settings changes to all open tabs

[roomote]

This PR addresses Issue #8634 by ensuring MCP settings changes are broadcast to all open tabs.

Problem

When MCP tool permissions or server settings are changed from a second Roo tab, the changes were not persisting and appeared to be applied to the original tab instead.

Solution

Modified McpHub.notifyWebviewOfServerChanges() to use McpServerManager.notifyProviders() instead of notifying only the current provider. This ensures all open tabs receive updates when MCP settings change.

Changes

• Updated src/services/mcp/McpHub.ts to broadcast changes to all providers
• Updated tests in src/services/mcp/__tests__/McpHub.spec.ts to mock McpServerManager

Testing

• All existing unit tests pass
• Manual multi-tab testing cannot be performed in the container environment

Note

This fix addresses the notification aspect of the issue. I have posted questions to the issue for clarification on whether additional changes are needed for:

• File write operations and persistence
• Race condition handling with concurrent writes
• Multi-tab integration testing

Fixes #8634
