feat: implement Metric.update() via PATCH /scorers/{id}

[thiagobomfin-galileo]

User description

Shortcut:

Implement Missing CRUD Operations in future Package

Description:

• Implements Metric.update() in the future domain layer, replacing a NotImplementedError stub that
  incorrectly claimed the API didn't support scorer updates
• Wires up the existing but unused update_scorers_scorer_id_patch endpoint (PATCH /scorers/{id}) with
  a partial-update pattern using UNSET-aware request bodies

Tests:

• Unit Tests Added
• E2E Test Added (if it's a user-facing feature, or fixing a bug)

---

Generated description

Below is a concise technical summary of the changes proposed in this PR:
Enable Metric.update to validate fields, send UNSET-aware payloads through update_scorers_scorer_id_patch, and refresh the metric instance after the partial PATCH call. Handle missing IDs, invalid arguments, and API failures by raising clear errors and updating the sync state so callers can distinguish success from retryable issues.
