Migrate off the deprecated bitcoincash 0.29 API (Amount/Version types,
FromHex -> FromStr/parse, non-exhaustive Network) across the indexer and
tests.
Add indexing of native token-A <-> token-B (TokenToken) AMM pools:
- tokentoken_pool / tokentoken_pool_history_entry tables in cauldron.db,
created via an always-run idempotent migration (no DB_VERSION bump, so
existing databases upgrade in place)
- block-path indexing sharing the cauldron write transaction and reorg
undo, with creation/swap/withdrawal state tracking and reserve deltas
- mempool indexing: electrum mempool.get filters on the tokentoken
contract code (spends) and the CONJURE op_return hint (creations);
first_seen_timestamp reconciles with mtp on confirmation
- RPC endpoints /tokentoken/pool/active (pair lookup, order-insensitive)
and /tokentoken/tokens

Migrate all 32-byte hash fields from TEXT (64-char hex) to BLOB
(32 bytes) for ~50% storage savings on hash columns.
Changes:
- Add src/db/blob.rs with ToBlob/FromBlob traits for hash types
- Update all table schemas to use BLOB for hash columns
- Replace .to_hex() with .to_blob() for DB inserts
- Replace ::from_hex() with ::from_blob() for DB reads
- Use SQL hex() function where API responses need hex strings
- Bump DB_VERSION from 4 to 5
Affected tables: tx, pool, pool_history_entry, utxo_spending,
utxo_funding, user_action, auth_chain_entry, bcmr_data,
bcmr_failure, bcmr_well_known, crc20, crc20_candidates,
delphi_entry, cached_token_metrics
