`price_oracle` is systematically omitted from build/release/monitoring tooling (`Makefile`, `wasm-size.yml`, `record-wasm-hashes.sh`, `health-check.sh`)

[OxDev-max]

Description

Across the operational tooling, price_oracle is the one contract that's consistently
forgotten, even though it's a full workspace member and is deployed by deploy.sh:

• Makefile:8: CONTRACTS := access_control invoice_nft marketplace financing_pool treasury risk_registry
  — price_oracle is absent, so make build-optimized never runs stellar contract optimize
  on it, and make sizes never reports its size.
• .github/workflows/wasm-size.yml (lines 50, 102, 131): the same 6-contract list is hardcoded
  three times — price_oracle's WASM size is never tracked or regression-checked, unlike the
  other 6 contracts.
• scripts/record-wasm-hashes.sh (lines 48-55): the CONTRACTS bash array also lists only the
  same 6 contracts — price_oracle's release hash is never recorded.
• scripts/health-check.sh: queries access_control, invoice_nft, marketplace,
  financing_pool, treasury, risk_registry — price_oracle's admin, or whether its prices
  are stale, is never surfaced in the health JSON.
• scripts/deploy.sh's own deployment-manifest JSON (lines 224-264) computes hashes for and
  writes an entry for 6 contracts — price_oracle, despite being deployed and initialized
  earlier in the very same script, is never added to "contracts": {...} at all.

By contrast, .github/workflows/interface-compat.yml (lines 52, 73, 92) does include
price_oracle in its CONTRACTS list — proving the omission elsewhere is inconsistency, not a
deliberate exclusion.

Requirements and Context

This means price_oracle — the contract responsible for the entire multi-currency conversion
feature — silently ships without WASM-size regression protection, without a recorded release
hash, without an address recorded in the deployment manifest (making it nearly impossible for
scripts/interact.sh, scripts/ttl_keeper.sh, or scripts/check_state_drift.sh to reference
it after deployment), and without any health/monitoring signal. Fixing this requires touching
every one of these 5 files consistently.

Suggested Execution

1. git checkout -b fix/price-oracle-tooling-coverage
2. Add price_oracle to Makefile's CONTRACTS variable.
3. Add price_oracle to all three CONTRACTS lists in .github/workflows/wasm-size.yml.
4. Add "price_oracle" to the CONTRACTS array in scripts/record-wasm-hashes.sh.
5. Add price_oracle address/hash/admin/pause-adjacent fields to scripts/deploy.sh's
   manifest output and to scripts/health-check.sh's aggregated JSON (e.g., surfacing whether
   its currently-registered prices are stale via a lightweight get_price probe for a known pair).
6. Cross-check scripts/ttl_keeper.sh and scripts/check_state_drift.sh for the same omission
   pattern and fix if present.
7. Run make sizes and make build-optimized locally to confirm price_oracle's WASM is now
   included in all reports.

Acceptance Criteria

• make sizes reports a size for price_oracle
• wasm-size.yml's PR comment/report table includes a price_oracle row
• record-wasm-hashes.sh records a hash for price_oracle
• deploy.sh's generated manifest JSON includes a price_oracle entry with address and WASM hash
• health-check.sh's output JSON includes at least the price_oracle contract address and admin
