Replace index_block/index_mempool with a single index_txs that takes an
Option<blockhash> (Some for confirmed, None for mempool). Add
delete_entries(blockhash) for reorg undo and to drop stale mempool state
before applying confirmed blocks. Replace has_txchain_tx with
has_indexed_tx; chain-follow now keys on ido_state.next_output_index
instead of the removed tracker map.
Remove the debug-only txchain RPC endpoints and the debug config gating.
Keep txchain_head as a public RPC field.

Replace the per-request get_ido_entry_aggregates SQL scan with running
totals carried in IdoActiveState: totalDemandAmount, totalSupplyAmount,
and totalDiscount. Initialized to 0 at the preinit->active transition and
incremented on each entry added; the rebuild path recomputes them by
replaying the txchain, so they self-heal.
Drop the now-unused get_ido_entry_aggregates DB fn, the IdoEntryAggregatesRpc
type, the /<id>/aggregates RPC handler, and its route registration.

Sum demand/supply amounts and count entries for an IDO, used to show
"raised so far" for active offerings where on-chain state keeps no
running total.

- electrum mempool fetch gains an ido filter: state machine spends
(IDO_SIGNATURE in scriptsig) union preinit announcements
(IDO_PREINIT_ANNOUNCEMENT_SIGNATURE in scriptpubkey)
- split tx scanning out of index_block into index_txs and add
index_mempool, which indexes with a -1 sentinel height;
txchain_trim_tracker leaves negative heights alone and the real
height replaces the sentinel once the tx confirms in a block
- block indexing now skips re-creating an ido already seen in the
mempool, only updating its tracker height
- mempool txs are kahn-sorted so txchain parents index before children

Change get_txchain_tx to take the public txid (a unique field) instead of
the non-public internal txchain item id, and promote it to a production
endpoint. Mount the two remaining debug endpoints (list_ido_txchain,
list_txchain_tracker_map) only when `debug = true` in the config.

List every active TokenToken pool (no pair filter) so the frontend can
present the set of pooled token pairs without probing each candidate pair.
Mirrors db_active_pools_for_pair minus the pair WHERE clause; served at a
distinct /pools path (the param'd /pool/active already matches param-less
requests via its Option guards, so reusing it would collide).

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

This makes the application fully async; freeing web server threads to
handle new connections when waiting on SQL queries.
Additionally sqlx will allow easier move to a different database if
needed in the future.
Includes some SQL optimizations as well (slow queries more easliy identifiable
with sqlx).
The previous commit tried to query bcmr_data table from the crc20
database connection, but bcmr_data exists only in the bcmr database.
Fix by introducing STATE_SKIP_HAS_BCMR to mark tokens that have BCMR
data. The CRC20 fetcher now queries the bcmr database separately to
find candidates with BCMR data, marks them in the crc20 database, and
skips them in future iterations.
Introduce a shutdown flag and Rocket fairing that signals background
threads to exit cleanly when Ctrl+C is pressed. Affects the indexing
thread, metrics updater, and block receiver loop.
