fix: prevent duplicate block attachment in sleeptime agents (#9150)

Browse Source 
Check if a block with the same label already exists before attaching
to sleeptime agents. This prevents UniqueConstraintViolationError on
the (agent_id, block_label) constraint when the same block is attached
multiple times due to race conditions.
