feat(qoder): show in Quota Tracker dashboard

Wire Qoder credits into the Quota Tracker card grid:

- Add `qoder` to USAGE_SUPPORTED_PROVIDERS so the connection passes the
  isUsageEligible filter at /api/providers/client and shows up in
  providerOptions on the dashboard.
- Reshape getQoderUsage so quota records (user, organization) live under
  `quotas` and scalar metadata (totalUsagePercentage, isQuotaExceeded,
  expiresAt) are siblings — the parser used to walk Object.entries(quotas)
  and would have rendered `totalUsagePercentage: 0.42` as a "0/0" row.
- Surface Qoder's expiresAt as resetAt on each quota record so the card
  shows when credits reset.
- Add a parser branch in ProviderLimits/utils.js: rename internal keys
  (user → "Personal", organization → "Organization"), drop empty org
  buckets so personal accounts don't render a misleading "0/0 Organization"
  row, and forward remaining/unit so the QuotaProgressBar can use them.
- Add Qoder's brand color (#EC4899) to ProviderLimitCard's color map.

42 tests still pass; build clean.
