Fix MCP exec permission display metadata

[GHX5T-SOL]

Summary

• route MCP permission requests through the MCP renderer when the tool name is present on rawInput
• include Claude Code MCP tool metadata on generic MCP approval requests
• add regressions for PostHog exec permission cards rendering as posthog - Read execute-sql (MCP) instead of a generic exec title

Fixes #2177.

### Issue 1 of 1
apps/code/src/renderer/components/permissions/PermissionSelector.tsx:34-36
The `claudeCode` property in the `meta` type annotation is no longer accessed directly — `getMcpPermissionToolName` now handles that path. The type can be simplified to only what `meta` is still used for (`codeToolKind`).

```suggestion
  const meta = toolCall._meta as
    | { codeToolKind?: string }
    | undefined;
```
