fix(server): name search in contact_get/product_get returns empty (drop 'like' wildcards)

[Vitexus]

Fixes #1.

Problem

contact_get(nazev=...) and product_get(nazev=...) always returned an empty set. They built the filter as nazev like '*{nazev}*'.

Root cause

AbraFlexi's like operator is a plain case-insensitive substring match and takes no wildcards. The *...* wrapping made AbraFlexi look for a literal * inside the value, so nothing ever matched.

Verified directly against raw AbraFlexi REST (record nazev = "AAA Tondaaa"): like '*Tond*' and like '%Tond%' → 0 rows, while like 'Tond', like 'ondaa' (mid-string) and like 'tond' (lowercase) → 1 row.

Fix

Pass the term as a bare substring: nazev like '{nazev}'. Applied to both contact_get (adresar) and product_get (cenik).

Verification (production)

• Before: contact_get(nazev="Voda") → []
• Correct query proven equivalent: evidence_get(evidence="adresar", filter_expr="nazev like 'Voda'") → Vodafone Czech Republic a.s. ✅

The evidence_get/evidence_list filter_expr passthrough is unaffected — it forwards raw expressions correctly.

Summary by CodeRabbit

• Bug Fixes
  • Improved name-based search for contacts and products so partial matches now work as expected without requiring special wildcard formatting.
  • Search behavior is now more intuitive and consistent, avoiding cases where search terms were treated literally.

📝 Walkthrough

Walkthrough

The filtering logic for the nazev parameter in contact_get and product_get was changed to pass the search term as a raw substring instead of wrapping it in wildcard asterisks, aligning with AbraFlexi's like operator semantics. Explanatory comments were added.

🐰 A wildcard once hid the name,
No match was found, oh what a shame,
Now stripped away, the search runs true,
"Voda" finds Vodafone anew,
Hop, hop, the filter's fixed again!
