fix(ui): handle single-line markdown tables and pipe-delimited tables

- parseMarkdownTable now handles tables stored as single line by
  counting columns from separator row and grouping cells accordingly
- Added isPipeTable detection for pipe-delimited data without header
  (e.g., "1 | name | qty\n2 | name | qty")
- Added renderPipeTable for headerless pipe tables
