open_new_round_if_needed now withholds opening the next round until
ROUND_COOLDOWN_SECONDS (default 30) have passed since the previous
round's closed_at, returning None in that window instead of a Round.
Without this, the next round opened within one scheduler tick (~5s) of
the previous payout confirming — not enough time for a player to
notice the round they were in actually resolved.
Callers updated: the scheduler treats None as "nothing to do this
tick", and place_bet raises a "try again shortly" BetError instead of
crashing on a None round.
Not in the original flowchart — a deliberate UX addition on top of it,
documented as such in CLAUDE.md.

Bearer-token-gated admin endpoints to read/update the DB-backed
operational config (fee_address, bet_amount_sats) without a redeploy,
plus a lightweight audit log writer for round/payout/config events.

Builds and broadcasts a user->external-address PSBT with change back to
the user's own address, fee deducted from the withdrawn amount, and
registers the confirmation handler that marks the withdrawal confirmed.
Shares the per-user lock with bets so a build never races a spend from
the same UTXO set.

Periodic scheduler (configurable round duration) that closes a round
only once all broadcast bets confirm, waits for the next block after
closing, draws a winner via block-hash-seeded modulo over participants
ordered by broadcast time, triggers the 70/30 payout, and only opens the
next round once that payout confirms. Draw logic is isolated in
draw.py as a deliberately simple, replaceable component.

Places the fixed-cost bet into the current round: builds and broadcasts
the user->pool PSBT with change back to the user's own address, enforces
at most one active bet per user, and registers the confirmation handler
that marks a bet confirmed and adds the participant to the round.

Credits a user's internal balance once a UTXO on their deposit address
reaches 1 confirmation, keeping utxo_events as the source of truth and
cached_balance_sats as a derived read cache.

Shared per-user locking to serialize bet/withdrawal PSBT builds
(tx/locks.py), a confirmation poller for pending outgoing transactions,
and the timeout->fee-bump->rebroadcast loop used by bets, payouts and
withdrawals alike (tx/broadcast.py).

Minimal Electrum protocol client (client.py) plus a scripthash
subscription listener (listener.py) that watches user deposit addresses
for confirmed UTXOs, with the address->scripthash conversion helper and
a manual smoke-test script against the dev bootstrap server.

BIP84 derivation of per-user P2WPKH addresses and the pool address from
the encrypted master xprv (app/wallet/hd.py, keystore.py), the PLM
mainnet chain params (plm_network.py), and PSBT construction for bets/
payouts/withdrawals with change-output and fee-estimation logic
(psbt_builder.py).
