Migrate OSS toolkits to MCPApp (#782)
<!-- CURSOR_SUMMARY -->
> [!NOTE]
> **Medium Risk**
> Touches multiple toolkits’ runtime entrypoints and context/error/auth
plumbing, so breakage risk is mainly around invocation/packaging and
tool execution wiring rather than business logic.
> 
> **Overview**
> Migrates the BrightData, ClickHouse, LinkedIn, Math, MongoDB,
Postgres, and Zendesk OSS toolkits from `arcade-tdk` to
`arcade-mcp-server` APIs by updating tool decorators, `Context` types,
auth classes, and exception imports.
> 
> Adds per-toolkit `__main__.py` files that construct an `MCPApp`,
register module tools, and run via configurable transport/host/port;
corresponding `pyproject.toml` updates bump versions, drop
`arcade-tdk`/`arcade-serve` deps, and add `project.scripts` console
entrypoints.
> 
> Updates tests and eval suites to use `arcade_mcp_server.Context`
(mocked) and switches eval `ToolCatalog` imports to `arcade_core`.
