fix(packs): remove unfiltered pre-count in GET /packs (3 round-trips → 2)

Browse Source 
Remove Pack.select().count() on the unfiltered table at the top of GET
/api/v2/packs. This check raised 404 if zero packs existed globally —
wrong for filtered queries where no match is the expected empty-list
result. The filtered count at the end of the handler already handles
the empty-result case. Endpoint now returns {count: 0, packs: []} on
empty filter matches (standard REST pattern) and saves one DB round-trip
per request.
