v0.5.50

Fix

Model modal on runs launched before a model's card was set. A run started after model cards existed (v0.5.46) but before a model's card was filled in under Connections recorded an empty identity. Its model modal then showed no model card and no benchmark for that model, even after the card was set later.

Such runs now show the model's current card and leaderboard, the same as runs from before model cards existed. A run that recorded a real card still shows the card it ran with. The agent's base model on agent runs follows the same rule.

Upgrade note: no migrations.
