fix(docker): add mcp.run() call and update Docker instructions

Fixes Docker container exiting immediately by:
- Adding mcp.run() call to main() function to start FastMCP server
- Updating README Docker instructions to include -i flag for STDIO transport
- Removing unused port mapping (STDIO doesn't use HTTP ports)

The FastMCP server uses STDIO transport by default, which requires
an interactive stdin to remain running. The -i flag keeps stdin open
even in detached mode.

Fixes: TypeError and container exit issues reported in #issues
