Summary

Brings the Python client (clients/python) to endpoint parity with the Go client (clients/go) by adding typed models and client methods for /status, /nfts/*, and /webhooks/*.

Closes #312

Changes

1. clients/python/wraith/models.py & clients/python/wraith/__init__.py:
   • Added Status (ok, last_indexed_ledger, latest_ledger, lag_ledgers, started_at, uptime_seconds, total_indexed, status, network).
   • Added NftTransfer (NFTTransfer), NftTransferPage (NFTTransferPage), NftOwner (NFTOwner), and NftMetadata (NFTMetadata).
   • Added WebhookSubscription, WebhookSubscriptionList, WebhookDelivery, and WebhookDeliveryList (WebhookDeliveryPage).
2. clients/python/wraith/client.py:
   • Added WraithClient.status() (GET /status).
   • Added WraithClient.nft_transfers(...) (GET /nfts/transfers) and WraithClient.nft_owner(contract, token_id) (GET /nfts/owners/:contract/:token_id).
   • Added WraithClient.webhooks() (GET /webhooks), WraithClient.webhook_deliveries(webhook_id, ...) (GET /webhooks/:id/deliveries), WraithClient.create_webhook(...) (POST /webhooks), and WraithClient.delete_webhook(webhook_id) (DELETE /webhooks/:id).
3. clients/python/tests/test_client.py & clients/python/README.md:
   • Added offline responses-stubbed unit tests covering /status, /nfts/transfers query serialization & pagination parsing, /nfts/owners/:contract/:token_id metadata parsing, /webhooks & /webhooks/:id/deliveries, and POST/DELETE webhook lifecycle.
   • Updated clients/python/README.md usage examples and coverage table.
