feat(i18n): add tformat Jinja2 filter for parameterized translations

Browse Source 
Adds _tformat(s, **kwargs) filter registered as app.jinja_env.filters["tformat"].
Uses str.format_map() with named placeholders.

Usage: {{ t.key | tformat(count=total_suppliers, name=supplier.name) }}
JSON:  "Browse {count}+ suppliers from {name}"
