fix(beszel): MCP description accuracy and type strictness

- Add .default("1h") to timePeriod so MCP clients can omit it
- Include "1m" in the description's valid timePeriod values
- Clarify that getSystemStats uses only the first integrationId
- Use MantineSize type instead of plain string for itemRadius
