Add durable portfolio metrics

Proof: Persist portfolio value and PnL snapshots from the live inventory and reference-price path so operators can inspect trading performance from repo-controlled data.
Assumptions: The last credited inventory snapshot before the first live command is the correct baseline for trade-driven PnL, and EURe remains explicit 1:1 with EUR.
Still fake: The new portfolio metrics and watch output are implemented and tested locally but are not live until the updated app image is deployed to k3s.

+```
+
+The watch command tails the live market-maker loop through PostgreSQL history plus
+service `/state`:
+
+- matching quotes from `swap_demand_events`
+- decisions from `trade_decisions`
+- emitted commands from `execute_trade_commands`
+- execution results from `trade_execution_results`
+- current credited BTC and EURe inventory
+- current strategy and executor arming state
+
+Use `--heartbeat-every 30` or a larger value if you want less idle output.
+
+Portfolio metrics:
+
+- `history-writer` now derives durable portfolio metrics from the latest inventory snapshot plus the latest reference price.
+- The PnL baseline is the last credited inventory snapshot before the first live `cmd.execute_trade`.
+- `trade_pnl_eure` keeps the baseline BTC price fixed to isolate execution PnL from later BTC moves.
+- `mark_to_market_pnl_eure` values both the baseline and current books at the latest reference price.
+- `price_move_pnl_eure` is the difference between those two, so operators can separate execution edge from subsequent BTC repricing.
