feat(catalog): auto-purge orphan materials when quotes/items release them

A material that ends up referenced by nothing (no line_items anywhere, no warehouse stock) was previously left behind forever, accumulating dead catalog rows as offers were edited or deleted.

- new quote_service.cleanup_orphan_materials(db, material_ids): for each candidate it checks usage across line_items (all quotes) and warehouse inventory; only when both are zero does it remove the auxiliary rows (supplier_materials, brand_materials, material_units, material_attribute_values) and finally the materials row; returns the purged ids
- replace_quote_children (edit modal): snapshots the quote's material ids before the children are replaced, diffs against the incoming items, and purges whatever was detached
- delete_quote: collects the quote's material ids + attachment keys first, deletes the quote, purges orphans inside the transaction, and only then (post-commit) removes the MinIO objects — now both the recorded attachment keys and a recursive remove_prefix(quote_id/) sweep, so stray objects under the quote folder cannot survive; the response's cascaded block reports purged_orphan_materials
- line_items: PATCH that switches a line item's material, and DELETE of a line item, both clean up the previously referenced material
- storage.remove_prefix(prefix): best-effort recursive object deletion under a prefix (sync MinIO client wrapped in asyncio.to_thread, same pattern as remove_object)

Safety: usage checks run against the whole system before any delete, so shared materials — including those held only by warehouse stock — are never touched. Verified: python compile + api image build clean.
