feat(filters): split time filter into hands-on and total time (kiwi#52)

Adds max_active_min request field and backend filter. Active time uses
parse_time_effort().active_min (passive waits excluded). Recipes with
no parsed active time signal are not excluded (avoid hiding unlabelled
results). Total and active limits are AND'd when both set.

UI: two pill rows — "Hands-on time" (15/30/45/1hr) and "Total time"
(30m/1hr/90m/2hr/3hr/4+hr). Replaces single row capped at 90 min.
