Switch AuthorizationAttributes to batch and add AuthorizeBatch

Change AuthorizationAttributer.AuthorizationAttributes to take a slice
of resource ids and return policy.AttributesByID, so a single SQL
round-trip can load condition attributes for a whole batch. All
coredata implementations are migrated to a single
`WHERE id = ANY(@resource_ids::text[])` query that returns only the
rows it finds.

Authorizer gains:
  - AuthorizeBatch — all-or-nothing across a homogeneous (same entity
    type, same organization) resource set; rejects mixed entity types,
    mixed organizations, and empty batches with structured errors.
  - AuthorizeMulti — heterogeneous evaluation that returns one error
    per item and writes audit log entries in a single bulk insert.

The single-resource Authorize is rewired to delegate to AuthorizeBatch
so all paths share the same condition evaluation and audit logging.
recordAuditLog is split into buildAuditLogEntry plus a batch insert.

Tests cover the new batch and multi paths, mixed/empty/unsupported
resource cases, audit log batching, and dry-run behaviour.
