Summary
Added FileMetadata dataclass and extract_file_metadata fn alongside the existing type detection helper. Callers can now get structured info (row/column counts for tabular formats, dimensions for images, file list for archives, encoding for text) in one call instead of just a type string.

Changes (by file)
Briefly list the important modified files and what was done.
DashAI/back/tasks/utils.py: added FileMetadata dataclass, five private per-type extractor fns (text, csv, json, image, archive), and the public extract_file_metadata fn that ties them together.Notes (optional)
PIL is imported lazily inside the image extractor so it stays optional. CSV detection uses csv.Sniffer as a fallback for plain text inputs that turn out to be tabular. Archive listing is capped at 50 entries to avoid huge payloads.
