Rename MCPServer CRD Port Attributes for Clarity

[ChrisJBurns]

• Rename port to proxyPort - represents proxy runner port
• Rename targetPort to mcpPort - represents MCP server port

This change addresses user confusion about port semantics as discussed in issue #1452. The new names clearly indicate which port corresponds to which component:

• proxyPort: Port exposed by the proxy runner in Kubernetes
• mcpPort: Port that the MCP server listens on internally

Updated all relevant files:

• CRD types definition and generated YAML
• Operator controller logic
• All example and test YAML files
• Keycloak deployment example
