Add MCP HTTP Server Experiment

This PR adds a new experiment flag mcp-server-http to enable the MCP HTTP server functionality. The changes include:

  1. Added a new experiment constant ExperimentMCPServerHTTP with the value "mcp-server-http"
  2. Added display name and documentation for the new experiment
  3. Improved the experiment middleware to:
    • Support requiring multiple experiments
    • Provide better error messages with experiment display names
    • Add a development mode bypass option
  4. Applied the new experiment requirement to the MCP HTTP endpoint
  5. Replaced the custom OAuth2 middleware with the standard experiment middleware

The PR also improves the Enabled() method on the Experiments type by using slices.Contains() for better readability.
