feat: add blob tx listener

[hal3e]

Adds a new service state_listener which will periodically check if the pending blob tx are finalized.

The sql tables for blob support have been updated and look like this:

CREATE TABLE IF NOT EXISTS l1_submissions (
    id                SERIAL PRIMARY KEY,
    fuel_block_hash   BYTEA NOT NULL,
    fuel_block_height BIGINT NOT NULL UNIQUE CHECK (fuel_block_height >= 0),
    CHECK (octet_length(fuel_block_hash) = 32)
);

CREATE TABLE IF NOT EXISTS l1_fragments (
    id            SERIAL PRIMARY KEY,
    fragment_idx  BIGINT NOT NULL CHECK (fragment_idx >= 0),
    submission_id INTEGER NOT NULL REFERENCES l1_submissions(id),
    data          BYTEA NOT NULL,
    created_at    TIMESTAMPTZ NOT NULL DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE IF NOT EXISTS l1_transactions (
    id    SERIAL PRIMARY KEY,
    hash  BYTEA NOT NULL UNIQUE,
    state SMALLINT NOT NULL,
    CHECK (octet_length(hash) = 32)
);

CREATE TABLE IF NOT EXISTS l1_transaction_fragments (
    transaction_id INTEGER NOT NULL REFERENCES l1_transactions(id),
    fragment_id    INTEGER NOT NULL REFERENCES l1_fragments(id),
    PRIMARY KEY (transaction_id, fragment_id)
);

The sql queries are updated but the functionality remained the same. The new tables make it easier to update the tx state and query for finalized submissions (thans @segfault-magnet for the idea).

LGTM! Left just a small question.

Another question: If I'm not missing anything, this listener simply updates a db table with the status of a tx, but it doesn't perform any action to fix (e.g., retry) failed txs. Is that right?

Yes. The state-commiter will handle failed fragments and create new txs. The state-listener will fetch all pending tx and check their status and update the db.
