fix(sequencer): submit genesis block to Bedrock on fresh start

Browse Source 
The sequencer created the genesis block's inscribe transaction but
discarded it (`_tx`), never posting it to Bedrock. The indexer's
`search_for_channel_start` scans backward through L1 blocks looking
for an L2 block with `block_id == 1` to locate the channel start. Since
genesis was never on L1, the search looped indefinitely, clearing its
buffer on every cycle, and `current_state` was never updated past genesis.

On a fresh DB start, submit the genesis block to Bedrock immediately
after creating it, mirroring what `produce_new_block` does for all
subsequent blocks. On restart the genesis block is already on Bedrock
from the initial run, so submission is skipped.

Fixes the `indexer_state_consistency` integration test.
