Fix/indexer parser hardening

[janetpius-cmd]

• Resolution parser (resolutionParser.ts): legacy dev-stub payload shapes (ScvVec tuple, legacy ScvMap) are now rejected with ResolutionParseError when NODE_ENV=production, instead of silently producing ResolutionCandidate rows with a blank oracleAddress. Emits indexer.parser.legacy_shape_rejected.
• Trade parser (tradeParser.ts): buy_order_id/sell_order_id are now validated — always rejects empty ids, and in production requires a UUID shape matching Order.id, so a fill that can't join to a real CLOB order fails the batch instead of persisting unlinked. Emits indexer.parser.unjoinable_order_id.
• Collateral deposited parser (collateralDepositedParser.ts): amountRaw is now validated against the same 7-decimal/Decimal(20,8) bounds decimalUtils.amountRawToDecimal uses elsewhere, rejects zero/negative amounts, and in production rejects amounts that decode as a plain number instead of the expected i128 bigint. Emits indexer.parser.invalid_collateral_scale.
• Retry classification (retry.ts): added classifyError() distinguishing fatal (parse/validation errors, non-429 4xx — never retried), rate_limited (429 — backs off harder, honors Retry-After), and transient (network errors, 5xx — standard backoff). Fixes the "parse errors retried forever" gap.
