feat: add prompt resources, fix MCP proxy transport, enrich tool descriptions

- Fix MCP proxy to support SSE and STDIO transports (not just HTTP POST)
- Enrich tool descriptions with server context for LLM clarity
- Add Prompt and PromptRequest resources with two-resource RBAC model
- Add propose_prompt MCP tool for LLM to create pending prompt requests
- Add prompt resources visible in MCP resources/list (approved + session's pending)
- Add project-level prompt/instructions in MCP initialize response
- Add ServiceAccount subject type for RBAC (SA identity from X-Service-Account header)
- Add CLI commands: create prompt, get prompts/promptrequests, approve promptrequest
- Add prompts to apply config schema
- 956 tests passing across all packages
