- Send comma-separated tariff_ids to backend (was only single ID)
— server now filters with IN() operator, pagination correct
- Remove client-side tariff filtering (server handles it)
- Add "Только триал" checkbox filter: amber checkbox, filters users
with trial subscriptions client-side
- Remove "trial" from status dropdown (was not working via
subscription_status server filter)
- i18n: trialOnly key (ru + en)
