Ensure admin key deletion removes the DB record and returns a
"deleted" status. Update seeder idempotency to count only active keys
when deciding whether to skip or create new keys.
Trim whitespace in provider model lists, format provider names as `group#keyID`
to match DP logs, and skip existing API keys during seeding (deleting on reset)
to keep runs idempotent and summaries accurate
- Parse provider group models from API response string and expose as slice
- Send `model` field (not `model_name`) when creating logs
- Use API key ID as `provider_id` instead of provider group ID
- Restrict reset behavior to resources matching seeder tag/prefix
- Refactor usage sample generation to accept a context struct
Introduce a `cmd/seeder` CLI to generate deterministic demo datasets and
seed them into the Control Plane via admin endpoints, supporting reset,
dry-run, profiles, and usage sample generation.
Add Cobra/Viper dependencies to support the new command.
