refactor: deduplicate MCP server, add object_id support, remove config tools

- Extract shared AnalysisType::from_api_name() and ComplianceType::from_name()
  so MCP reuses enum parsing instead of duplicating match arms
- Make resolve_analysis_id public, reuse from MCP instead of reimplementing
- All scan tools now accept object_id as alternative to scan_id, matching
  the CLI's --object flag and aligning with ELI's natural interaction model
- Remove configure_profile/config_get/config_set (config mutation is out
  of scope for AI agents); keep whoami for diagnostics
- Add [Read]/[Write]/[Critical] classification to tool descriptions,
  preparing for ELI's Permission Gate
- Fix &PathBuf -> &Path (Clippy), trim instructions block
