Summary

Closes GitLab #278 — indexer parity with onchain global lastBuyEpoch.

Persist LastBuyEpochStarted to idx_arena_last_buy_epoch_started
Assign idx_arena_buy.last_buy_epoch from ordered global head during ingest
Replace wallet-stats per-wallet timer_hard_reset window inference
Integration regression + bash scripts/verify-last-buy-epoch-anvil.sh
Docs: INV-INDEXER-278-LAST-BUY-EPOCH, guardrails/skills cross-links

Verification

Layer	Command	Result
Indexer clippy	`cd indexer && cargo clippy --all-targets -- -D warnings`	PASS
Indexer tests	`YIELDOMEGA_PG_TEST_URL=… cargo test`	PASS (4 integration)
Anvil smoke	`bash scripts/verify-last-buy-epoch-anvil.sh`	PASS

Leave #278 open for QA sign-off.
