chat_v0 returned the raw LiteLLM message, leaking provider-specific fields
(provider_specific_fields, annotations) into outputs. Validate through the SDK
Message model so the output is the canonical {role, content, name, tool_calls,
tool_call_id}, matching what a hook/custom workflow returns.

The API-key creation success popup rendered the full key in a flex row
without any break rule. A real key is an 8-char prefix plus a 64-char
hex secret (one '.' separator), so the unbreakable hex tail forced the
flex item past its container and the key overflowed the modal edge.

Let the key wrap within the available width and keep the copy icon
pinned beside it:
- key span: min-w-0 + break-all so it can shrink and break mid-token
- icon span: shrink-0 so it is never squeezed out
- row: items-start so the icon aligns to the first line when wrapping

Fixes #4645

get_default_workspace_id no longer prefers owner-role (multi-org: an
invitee owns their own empty personal workspace). Update the stale test
to assert the oldest membership wins regardless of role.
