Summary

Indexer hybrid pool sim uses wide k and skips implausible mixed 18/6 hops (ImplausibleHop → path unusable) so a funded shorter route can win.
Route cache keys already include token_in/token_out; 1 USTR (1e18) and 10000 USTR no longer share AMOUNT_CACHE_BUCKET.
Swap / Trade pin registry USTR / unique-symbol USDT (terra1z0xe7…) as 18-dec; unknown CW20 stays 6.
Expected slippage ≥ 99% hides You Receive and blocks submit. Expert Mode still waives > 30% only.

Fixes #1257

Test plan

make verify-issue-1257 (indexer hop sim + cache buckets; Swap 30%/99% Expert; docs greps)
Indexer lib: mixed 18/6 hop, implausible last hop, wide k, per-unit size curve, amount cache alias
Vitest: swapQuoteAmountScale, SwapPage 30% Expert waive + 99% theater, tokenRegistry/formatAmount USDT 18
Manual columbus-5 Swap USTR→USDT sizes 1 / 100 / 1000 / 10000: receive is size-monotonic, not billions
Confirm unique-symbol USDT ticker in the picker; no second USDT row
