The Minimax usage panel only rendered one model row. The primary `general`
model meters quota purely via `current_interval_remaining_percent` (its
`current_interval_total_count` is 0), so the count-based `total > 0` visibility
filter dropped it entirely. The percent was also derived from count fields
rather than the authoritative `*_remaining_percent` field.
fetchMinimaxUsage now builds windows via a helper that prefers
`*_remaining_percent` (count-based fallback when absent) and skips a window only
when no quota signal exists. Each model's separate weekly quota window is now
surfaced as its own indicator alongside the interval window.
Verified against the live coding_plan/remains endpoint: 2 models (general,
video) now produce 4 windows (interval + weekly each) instead of 1.
