Follow-up fixes on the agent-roles feature:
- ai.service: a cross-driver override to the ollama driver (when the
workspace driver is not ollama) now fails with an explicit 503 instead
of silently reusing the workspace base URL, which belongs to a different
provider. Same-driver ollama and openai/gemini overrides are unchanged.
- migration: add a partial unique index on (workspace_id, name) WHERE
deleted_at IS NULL so role names are unique per workspace without
soft-deleted rows blocking re-creation; map Postgres 23505 to a 409
ConflictException on create/update.
- dto: validate the role id as @IsUUID instead of @IsString.
- roles list: do not expose instructions/modelConfig to non-admin members.
The list endpoint now returns a picker view (id/name/emoji/description/
enabled) to members and the full view only to admins (same gate as the
CRUD endpoints). Client IAiRole fields made optional accordingly.
Adds tests for the cross-driver-ollama throw, the 23505->409 mapping, and
the non-admin picker-view security invariant.
