Summary

Default /trade and /charts UST1-as-asset_0 markets to the other token’s Price (USD) (cUSTC / USTR), with a pair-orientation pill and ticket invert icon sharing one sessionStorage-keyed state.
Remove the Order ticket eyebrow. Ticket heading is Buy {displayBase}. Bid/ask stay a separate radiogroup; invert is not LimitOrderSideFlipButton and does not steal PairSearchSelect click.
Convert display quote-per-display-base back to factory token1/token0 (and display Buy → factory ask when inverted) on place, update-price, crossing/price gates, and market quote/submit. Indexer #522 math is unchanged.

Closes #524

Test plan

make verify-issue-524 (run twice)
Vitest: invert helper, USD/OHLC, TradePage UST1 default + pill/ticket sync + pair-switch isolation, PriceChart pill + XSS text nodes
Reviewer: open /trade on columbus-5 UST1/cUSTC and confirm Last is cUSTC dollars, not ~$1
Click pill then ticket invert icon — chart, Last, and Buy {token} stay in sync
Place an inverted Buy cUSTC limit (sim wallet) and confirm on-chain/indexer price is factory quote-per-base, not 1/P
Pair search still opens from the combobox; invert does not fire on combobox click
/charts UST1 pair uses the same default + pill
Non-UST1 pairs default factory; invert still works
Keyboard: Tab to pill and icon, Enter/Space toggles; axe on /trade + /charts

## Summary - Default `/trade` and `/charts` UST1-as-`asset_0` markets to the **other token’s** Price (USD) (cUSTC / USTR), with a pair-orientation pill and ticket invert icon sharing one `sessionStorage`-keyed state. - Remove the **Order ticket** eyebrow. Ticket heading is **Buy {displayBase}**. Bid/ask stay a separate radiogroup; invert is not `LimitOrderSideFlipButton` and does not steal `PairSearchSelect` click. - Convert display quote-per-display-base back to factory `token1/token0` (and display Buy → factory ask when inverted) on place, update-price, crossing/price gates, and market quote/submit. Indexer `#522` math is unchanged.
