financial-analysis .mcp.json is invalid JSON (missing comma + brace) — breaks all 11 MCP connectors

**Plugin**: `financial-analysis` (vertical-plugins), version 0.1.1
**File**: `plugins/vertical-plugins/financial-analysis/.mcp.json`

### Bug
The `.mcp.json` file is invalid JSON:
- Missing comma after the `egnyte` server entry, before `box`
- Missing closing brace for the `box` object / root object

Confirmed with `JSON.parse`:

### Impact
Because the file fails to parse, Claude Code cannot register **any** of the 11 MCP connectors bundled in this plugin (Daloopa, Morningstar, S&P Global, FactSet, Moody's, MT Newswires, Aiera, LSEG, PitchBook, Chronograph, Egnyte, Box) — `claude mcp list` shows zero servers after installing the plugin.

### Fix
Add the missing comma after the `egnyte` block and close the `box` object / root object properly:
​```json
"egnyte": {
"type": "http",
"url": "https://mcp-server.egnyte.com/mcp"
},
"box": {
"type": "http",
"url": "https://mcp.box.com"
}
}
}
​```

Verified locally that this fix produces valid JSON and lets Claude Code register the connectors.
