refactor(mcp): improve data structure with metadata/spec separation

- Separate MCP server metadata from connection spec for cleaner architecture
- Add comprehensive server entry fields: name, description, tags, homepage, docs
- Remove legacy format compatibility logic from extract_server_spec
- Implement data validation and filtering in get_servers_snapshot_for
- Add strict id consistency check in upsert_in_config_for
- Enhance import logic with defensive programming for corrupted data
- Simplify frontend by removing normalization logic (moved to backend)
- Improve error messages with contextual information
- Add comprehensive i18n support for new metadata fields
