The last four MCP enabled-flag readers use the shared reader (ACP, hermes tools picker, desktop connector card, health sweep) (#119601)

* fix(mcp): ACP, `hermes tools` and the desktop connector card use the one enabled reader

#119567 left four readers of `mcp_servers.<name>.enabled` on their own rules.
@webtecnica's #119560 found the ACP one:

- `acp_adapter/session.py::_make_agent` used `is not False`, so an ACP
  session kept a server with `enabled: "false"` or `enabled: 0` in its
  toolset while the MCP client skipped it.
- `hermes tools` MCP picker (`tools_config_mcp._configure_mcp_tools_interactive`)
  read `enabled: 0` as on and crashed on a non-dict entry.
- Desktop connector card (`connectors/data/join.ts`) and the MCP health sweep
  (`store/mcp-health.ts`) used `enabled !== false`.

All four now call `mcp_server_enabled` (Python) or `serverEnabled` (renderer),
which share one case table.
