feat(data-profiling): real CSV parsing + stats, with mock fallback

DataProfilingService now fetches the actual dataset file via
DatasetService.retrieveDatasetVersionSingleFile (presign-download endpoint),
parses with papaparse (first 5000 rows for performance), and runs a new
pure-TS profiler that computes:

  - dtype inference per column (numeric / datetime / boolean / categorical / text)
  - per-column: count, missing, missingPercent, unique, plus dtype-specific stats
  - numeric: mean, median, std, min, max, ±3σ outlier count, 10-bin histogram
  - categorical/boolean: top-5 value counts
  - dataset-level: row-key duplicate count
  - Pearson correlation matrix across (up to 8) numeric columns

If the source isn't a dataset path or any step fails (fetch / parse / empty
headers), we fall back to the deterministic mock so the panel always renders.
The panel header now shows a short filename (full path on hover) and surfaces
fetch/parse errors inline.
