fix: normalize REPL search/doc responses and fix block insert

- REPL search: handle dict response (fixes KeyError when API returns {blocks: [...]})
- REPL doc list/tree: normalize dict responses before table output
- REPL block insert: use parent_id instead of previous_id
- status command: use live ping result instead of stale session state
