URL: https://github.com/apache/superset/pull/36992
### SUMMARY
The `health_check` MCP tool had a `ctx: Context` parameter that was not
being injected by FastMCP, causing "missing 1 required positional argument:
'ctx'" errors when calling the tool.
Since the function doesn't actually use the context, removing the parameter
entirely fixes the issue.
### BEFORE/AFTER SCREENSHOTS OR COVERAGE DIFF
**Before:**
```
Error calling tool 'health_check': health_check() missing 1 required
positional argument: 'ctx'

OSS MCP
Service","version":"0.0.0-dev","python_version":"3.11.9","platform":"Darwin","uptime_seconds":null}
```
### TESTING INSTRUCTIONS
1. Start the MCP service
2. Call the `health_check` tool without any parameters
3. Verify it returns a healthy status response
