fix: local ticker search for screener (Sectors companies/ 401s on sub)

- q= now searches universe table locally (ticker + company_name LIKE, order by close) instead of calling the Sectors companies/ endpoint, which returns SUBSCRIPTION_DOES_NOT_ALLOW on the current subscription and silently fell back to the full 780-ticker universe
- removes the broken name-fill cmd + scheduler/one-shot Screen() name enrichment (wasted credits, empty names)
- Screener UI: search card says 'kode saham', results still show company name when present
