fix: repair 38 test failures across 7 test files

- indicators_spec.lua: fix missing closing paren
- completion_coverage_spec.lua: match actual status string
- mock_nvim.lua: add vim.bo mock for buffer tests
- log_viewer.lua: JOIN priority, schema-qualified FROM
- editor/cell.lua: 28 fixes — parse_value, validate_value,
  is_editable_field, edit_state, JSON format, edit guards
- db_browser/tree.lua: add PK suffix for PK columns
- promise.lua: support two-arg constructor, fix finally_
  propagation, fix M.reject
