In `@shared/data/vaccine_library.json`:
- Around line 1020-1058: Several combined vaccine entries ("short_name":
"Tdap-Hib", "Tdap-IPV", "Tdap-Hib-IPV") include generic aliases "Tdap" and
"Adult Tdap" which collide with the standalone Tdap entry and prevent those
combinations from being indexed/searchable; edit the JSON entries for those
three vaccines and remove "Tdap" and "Adult Tdap" from their common_names
arrays, leaving only specific identifiers/brand names (e.g., "Tdap-Hib",
"Boostrix Polio", "Repevax", etc.), so the setdefault-based alias indexing will
not drop the combination vaccines in favor of the standalone Tdap.
