This update enhances the accuracy of product imports by making product name searches case-insensitive and utilizing a similarity ratio (90%) to reduce incorrect matches. This prevents issues like mis-matching products due to capitalization or similar names, leading to more reliable data import and improved inventory management.

Before this commit:

- Product retrieval during import relied on exact name match and substring (ilike) search.
- Exact name search was case sensitive, so values like `Network Cable` would not match `Network cable`.
- Substring matching could return unrelated products (e.g. `Wireless bluetooth speaker` gets matched with
  `Wireless bluetooth speaker battery`), leading to unrelated matches.

After this commit:

- Exact name search is now case insensitive, allowing matches such as `Network Cable` and `network cable`.
- Substring based matching has been replaced with a similarity ratio (90%) to reduce false positives and improve matching reliability against customer database product names.

Technical:

- Replaced `=` with `=ilike` in the exact name search domain to make the lookup case insensitive.
- Similarity ratio is computed using Python's `difflib.SequenceMatcher` on product names, with a minimum threshold of 90% to qualify as a match.
- Added system parameter for configurable product name similarity threshold.
